World Tanks fails to establish a connection. Unable to install a network connection

Instruction

Carefully learn the data you have about this server. To establish communication, you need to know its IP address and port with which the connection will be implemented. For most servers running with the HTTP protocol, the standard is port 80.

Other ports can be opened on the server - it all depends on which services are running on it. For example, FTP - 21 port, Telnet - 23 port, SMTP (sending mail) - 25 port, POP (receiving mail) - 110 port, etc. Many of these ports are potentially open to the connection, but when trying to establish communication may require enter the password.

How to find out which ports are open on the server? To clarify this, use - for example, NMAP or XSpider. You can search for network information and other scanners. For sample, enter the address 127.0.0.1 to the scanner and try scanning. You will receive information about ports open on your computer.

The actual scanning process can be carried out. different ways. For example, you can specify specific ports to search for specific services, and you can check all ports completely. By defining which ports are open on the server, you can try to connect to them.

To connect, you will need programs that work with the relevant server services. For example, if 21 port is open, you need an FTP client. When open 23, you will need Telnet. Scanning ports, you can find those used by remote administration programs - for example, Anyplace Control, Access Remote PC, DameWare NT Utilities, Remotelywhere, Radmin, VNC, etc.

Found open portYou can try to connect to it. Most likely, you will be asked to enter the password, but sometimes administrators do not change the default. For example, for the popular RADMIN program (port 4899), the default password is 12345678 or 123456789.

There are a lot of programs that allow you to select logins and passwords to similar services, but you should know that such activity is illegal and criminalized. Therefore, work with ports, the connection to which the server administrator allows. For example, FTP - on this protocol, you can successfully download large amounts of data, view the files available for viewing. A good FTP client is in popular file Manager Total Commander.

Network architecture is a complex system, the work of which can be accompanied by errors and malfunctions. Almost every active computer user has met with the inscription "Error access to the server", whether it is an unrecognized website or an application connection error.

First make sure that the connection is violated only with a specific server. Try connecting to another and view web pages in the browser. Perhaps a problem in connecting to the Internet, the settings of your connection or errors in the work of the provider. Restart the computer and network devices. If necessary, contact technical support Companies providing you with Internet services.

One of the most common causes is the use of an incorrect address. Make sure you enter the correct name of the web page or IP address. They could change or stop their existence.

The reason for the absence of the possibility of connecting to the server may be the impossibility of access to it for physical reasons. The computer can be disconnected by hardware, be broken, or a problem that connects the machine with the Internet may be in the system.

Another reason for the lack of communication may be a security policy. Your computer's IP address can be listed for one other reasons for a black list of server prohibiting all or some types of compound. On the other hand, there are no cases of causes of a compound prohibiting from the client. Make sure the antivirus programs or network monitors of your computer or server corporate network Do not block the address to which you want to connect.

If the link is built based on the use of client software connected to the server, refer to the developer's website and make sure that you use last version. Otherwise, update the program. If you use a non-original, but server-compatible client program, then try to install other software options or the original version of the product.

Connection error can be associated with a trace to the server. Use the appropriate check commands. Perhaps the connection request to the server simply does not reach the addressee due to problems in intermediate nodes.

"Unable to install a network connection in WOT. It is possible that the server is unavailable or required checking the settings of the network connection. " Do you know this message? Then you are here. This message may occur on hundreds of reasons. In this article, I will try to reveal the main of them.

At the very beginning I would like that you would clearly understand the decryption of this message. Although there is something particularly nothing to understand. Tanks swear on the fact that you either do not have the Internet, or the client for some reason cannot find a connection with the gaming server. That is, you launched the client, in turn, trying to enter the Internet and navigate your server on a previously known IP address, but the server does not respond to him and the error message is displayed accordingly. Next, for clarity, we will analyze exactly how to connect the procedure for connecting to the game server:

Now, I hope everyone is clear a scheme for which you need to find a problem that prevents the client to connect to the server. Let's go further ...

By the way, more details about the bundle router -\u003e Provider -\u003e Game Server I told in the article, because This equipment affects greater in the "lags and friezes" in the game. If you have a very high ping, then the grace please read.

How will we fight?!
But, the first stage will be the entrance to the portal of Vargeiming dedicated to tanks. Well! And what if there are some work on servers now. About this developers are reported in advance and even describe the time during which the servers will not be available and all of which they place on their own website, so do not hesitate and go.

Next, we go according to the "Scheme". After the game client, the first obstacle is a firewall. Turn off it (instruction) and try to enter the game. Happened? Congratulations! Play with a disabled firewall or read the article Next.

So, we set the perpetrator. Now you need to open ports and create rules for this "chalunca" (WINDOVS Firewall). But first I will do the same in automatic mode.

Go swing .bat. File from Varyming Server:

This is not a virus, do not worry. You can open it notepad ++ and make sure. Here is its contents:

@Echo off set arg1 \u003d "% ~ d0% ~ p0worldoftanks.exe" set arg2 \u003d "% ~ d0% ~ p0wotlauncher.exe" IF Not Exist% Arg2% Goto Errorwotl Netsh Firewall Add AllowedProgram% Arg2% Wotlauncher Enable All Netsh Firewall Add Portopening UDP 20010-20020,32800-32900,12000-29999,50,12000-3478,3479,3432,30443,53,6881-7881,1900 WOT-UDP Enable Netsh Firewall Add PortOpening TCP 80,443,5222,523,6881- 7881 WOT-TCP Enable IF Not Exist% Arg1% Goto Errorwot Netsh Firewall Add AllowedProgram% Arg1% Worldoftanks Enable All CHCP 1251\u003e NUL Set Text_y \u003d "worldoftanks.exe" and "wotlauncher.exe" successfully added to the list of firewall exceptions.

Make sure the game client is updated to the latest version. CHCP 866\u003e NUL ECHO% Text_L%: EXIT PAUSE

Now run the game and try to connect to any server. How? Works? We defeated the message "Cannot install a network connection in WOT", Hurray! We go to play and no longer score your head! If not earned, then we go to do everything in manual.

In order for the message "Not be able to install a network connection in WOT" no longer arose, it is necessary that for the launcher and the client of the game in the firewall, some ports were opened, here they are:

For worldoftanks.exe:
- UDP bands with 32,800 to 32 900, from 20 010 to 20 020 and UDP port 53;
- TCP ports 80, 443.

For the work of the voice chat, it is also necessary for worldoftanks.exe to open a UDP range from 12,000 to 29 999 and ports 5060, 5062, 3478, 3479, 3432, 30443.
To work a text chat, you need to open TCP ports 5222 and 5223 to work for WORLDOFTANKS.EXE.

In addition, you can enable for worldoftanks.exe UDP protocol and TCP protocol on any ports in both sides, thus allowing firewall Skip to the client of the game any packages on any addresses.

For wotlauncher.exeyou must open:
-UDP ports 53, 6881, 1900.
-Tcp ports 80, 443, 6881.

Well, how did it happen? If, yes, I'm glad for you. Well, if not, then we do not despair and read more ...

The next obstacle on the connection path to the server is antivirus. If you do not have it, then we skip this paragraph.
Try adding the game folder to the trusted zone of your antivirus. But before this, check your computer for viruses.
All different antiviruses are different, according to this, the developers team wrote for us a whole book with instructions, a link to which I am here and bring. (Thank you so much for Titanic Labor)
How to add a game client to the list of antivirus exception.

You can still (but not necessarily) add a list of IP address IP addresses.

Servers RU1-RU9:
92.223.19.1 - 92.223.19.255

Ranges of addresses of servers required for voice communication:
64.94.253.1 - 64.94.253.255
74.201.99.1 - 74.201.99.255

In some cases, turning off the antivirus and firewall does not lead to a solution to the problem - ports remain closed.

Here either nethewuha Palcisedor self windows already horse moves By the way, because of this may appear lags and brakes in the game. How to cope with them is written. Now let's try to reset the TCP / IP network settings and all sockets from the command windows strings With the help of the team Netsh WinSock Reset.

Run the command line:

- For Windows XP: Click Start\u003e Run. In the window that opens, type cmd.exe and click OK.

- for Windows Vista. And Windows 7: Click Start, enter the CMD in the Start Search field, press the CMD.exe file with the right mouse button and select "Run from the administrator name".

- For Windows 8: on the desktop, press the WIN + X key combination. In the menu that opens, select "Command Line (Administrator)".

Enter B. command line Team netsh Winsock Reset. And press ENTER.

Now it remains only to restart the computer.

Well, how are you with the message "Do not manage to install a network connection in WOT"? Victory? Hurray !!! keep it up! Well, now you can both in battle! Good luck on battlefield Dear tankers and tankers!

We share in the comments. What method helped you ...

Probably there is no such young man in Russia who did not hear about World Of Tanks - the online game in real time in the genre of the arcade tank simulator based on World War II. Fascinating gameplay, combining shooter, strategy and role-playing game at the same time, attracted millions of fans around the world. As a result, the tanks became the most popular online game 2012, 2013 and 2014. And even now interest in it does not weaken. Unfortunately with the game sometimes problems occur due to which WORLD OF TANKS does not start And gamers are sad. So so that they do not get upset and did this post. The fact is that usually tanks do not work because of one of a certain number of the most common reasons, which I will tell now.

1. Tanks do not start

You click on the label, but nothing happens - zero reaction.
To begin diagnostics it is necessary to check whether the launcher works - special utilitythat runs all software modules. To do this, go to the folder with installed playing (usually c: \\ games \\ world of tanks) and start the executable file in it worldoftanks.exe.. Here it is:

If the game after that started, then the problem is in it. Launcher bootloader is called he Wotlauncher.exe. And lies in the same folder:

It may not work due to the fact that is blocked by the computer security system. This happens because proactive protection sees that some application constantly climbs into the Internet and downloads something. This behavior seems suspicious and the application is blocked. Try temporarily disable the antivirus and check the game.

Note:

In some cases, the antivirus can skip the launcher, but to delete the game file itself. Then a warning will be issued - "The launch of the game is impossible. There is no WORLDOFTANKS.EXE file "

In this case, it will be necessary to go to the settings of the antivirus, restore remote file. From quarantine and add it to exceptions.

Common causes of game start errors:

If tanks do not start even directly - remember what you did before it with a game or computer.

- Very often the cause of the failure is new fashion. The WOT folder will be the RES_MODS directory. Its content must be cleaned and again try to run the program.

- Maybe you updated Drivers or DirectX?! In this case, you need to try to roll back to old version Or use a point windows restorationwhich will allow you to return to previous state operating system.

- Check the relevance of the drivers for the video card (NVIDIA, RADEON) and DirectX. Update them if there are new versions.

- For the normal operation of the game, the Visual C ++ 2015 library package must be installed on the computer and .Net Framework. version 4.0.. Without them, it may not start or issue various errors.

- Try fully reinstalling the game. Remove the available copy, then download the installer from the official site and put the game on the PC again.

If you first installed the game and the World of Tanks does not start - check if your computer meets system requirements:

At least 36 GB free space On disk. - At least 2 GB of RAM. - Minimum Internet speed 256 kbps. - GEFORCE 6800 / ATI HD 2400 XT video cards with 256 MB of memory. - DirectX not older than 9.0c. - Dual-core processor supporting SSE2 technology.

Script errors when running World of Tanks

This kind of fault occurs in the browser due to the fact that the game fails to start the script without which it cannot work.
Usually the reason for the appearance of the scenario error is the security system of the operating system. Roughly speaking, the antivirus blocks the work of scripts and scenarios, regarding them as unsafe. Therefore, try to deactivate antivirus for a while and checking the game.

If World of Tanks still does not start with the script error - try updating the browser, you may have a sufficiently ancient version that incorrectly implements interaction with the game files.

Do not forget that as a result of software or even hardware failures, the scenarios themselves may be damaged. It usually helps a complete reinstalling game.

WORLDS OF TANKS customer update error

The avid "tankers" at least once, but faced with errors of updates in tanks.

The causes of the WOT update error occur:
- Unavailable server with game updates
- Problems with Internet access
- Error with updates of certain modes or a specific game configuration.
To eliminate the first two reasons, you will have to "kick" the technical support of its provider. But to remove the failure associated with the mods, you have to try to remove fashion games, as I said earlier, and watch the result.
In some cases, it saves only reinstalling the program.

Error D3DX9_43.DLL, XC000007B, 0x00000003, etc.

All errors launch World of tanks associated with system files and libraries are a consequence of problems that have arisen in the operating room windows system. For example, the error d3dx9_43.dll usually means the DirectX failure, and the XC000007B error is related to damage system files or change settings.

The same can happen in the event that the virus is in the system.
The advice here is the ladies - check the OS good antivirus. - DrWeb Cureit or Kaspersky Virus Removal Tool, then set the latest version of DirectX and update the video card drivers.

Restoration of the game

If you have a launcher without any problems, but the tank game itself does not start, that is, another option that is integrated by the developers. To use them, go to "Settings" and go to the Support tab.

Here will be the "Check" button. By clicking on it, we will run the process of checking the integrity of the game files. If the problem is detected - the file will be restored.

P.S.: If none of my tips helps you, then do not forget that the game has an excellent support service, which can also help you. It is only necessary to properly describe the problem and prepare several screenshots, where the launch error of the Tanks raft will be displayed. After that, go to the official website in the "Support" section and create a new application.

Stable I. fast access In the World Wide Web - it is not yet a guarantee that you can unhindered to visit your favorite Internet resources. The error "cannot establish a connection with the site" often appears at the most unexpected moment.

The essence of the error is that on the computer or on all devices connected to one router, sites are stopped opening, although there is a connection to the Internet. Let's talk that it may be the reason for identifying the culprit and what measures to take to eliminate.

No access to all sites

Opening errors sites arise through a variety of reasons. To the first group, we will take the situation when the browser cannot access either one Internet resource. This group meets more often and its causes are more diverse than in cases when only certain sites are not opened.

Causes of lack of access

PC or router network settings failure (can be entered by a user or software, including malicious).
Damage to the components of the OS network subsystem (there is a consequence of the user actions, the operating system failure, infection and delete files of this structure malicious program, lock or removal by antivirus).
Incorrect firewall settings (firewall) or parental control facilities (browser is prohibited internet access).
Very low speed or internet connection.

Connecting to the network through incorrectly working or low-speed proxy and VPN.
Incorrect settings or browser failure (including installation of "curves" of extensions and user scripts).
The activities of malware (except for changing network parameters and components, the virus may not be incredigice to block the loading of sites).
Issues on the side of the Internet provider.

How to calculate the culprit

Analysis of the events that preceded by him will help you think about the culprit of the failure.

If the error appeared:

any actions with the router: replacement, repair, firmware update, change settings, etc.;
changing the PC network connection parameters (for example, new DNS addresses were prescribed;
installation or removal of programs that interact with network structures (Internet accelerators, traffic analyzers, 3G / 4G modem applications, etc.);
manual or software cleaning system from garbage, optimization, removal of "viruses" using antivirus utilities, registry edits, change group policies,

the most likely reason is incorrect settings Network or damage to network components.

If before the failure, I took place:

installing or deleting a firewall or anti-virus program with built-in firewall;
changing the firewall settings (firewall);
installation or reconnaissance of parental controls;
the appearance of non-safe connection messages with a proposal to strengthen protection,

the culprit is most likely antivirus, firewall (firewall) or a means of parental control.

If an event is accompanied by:

spontaneously popping advertising;
violation of system functions;
errors when performing normal operations (opening folder, copying, etc.), which were not before;
alerts antivirus program;
lOST ACCESS K. electronic wallets and accounts on the Internet that you used on this PC;
other unusual phenomena that was not observed before

the reason is most likely in viral infection.

What to do next

The procedure for diagnosing and eliminating the failure below covers all the listed causes. If you have an assumption about a particular culprit of the problem, you can only perform the actions that are suitable for your case. If the previous one did not help, go to the next one.

Restart the router. Check the Internet connection settings, black and white site lists, DNS addresses. If the specified DNS is unknown to you, write the address of your provider or or Google instead of them.

Check the network connection parameters on the PC. The main gateway must be specified. DNS servers addresses (if not automatically assigned) must match the IP of the main gateway, belong to your Internet provider or be public.
If you use to go to the global vPN network Or proxy, disconnect them.
Make sure the Internet connection is stable and sufficient connection speed using, for example,.
Make reset network settings. To do this, run the system application " Parameters", Go to" Network and Internet»And on the right side of the window, click" Reset network" Click " Reset now" This action reins Ethernet and WLAN adapters and restore the original parameters of all network components. After executing the reset operation, the computer will restart.

Temporarily disable firewall or firewall, as well as parental control means if you use. To disconnect the Windows Firewall 10, run " Parameters"Open" Update and security» – « Windows security" Right click " Network Firewall and Protection" In the defender security center window, which opens next, click the connection marked as " Active" Next, move the firewall slider to the position Switched off».

Check if there is a problem in other browsers. If it is present only in one, most likely, the reason lies inside the browser itself. Check your Internet connection settings (if you do not use proxy and VPN, but they are spelled out in the browser settings, delete these records), disable extensions and user scripts ,. If nothing helped, export bookmarks and reinstall the browser.
To exclude the active impact of working programs (including malicious), with network support. If access to sites will be restored, the reason in the programs. It remains to find which one. However, if the failure causes the changes made to the system, it will not help them reveal and remove, as they retain an action even without the presence of their programs. To combat change, use the following method.
For the day, when sites opened without errors.

Scan antivirus discs.
If the problem occurs on all devices connected to the network of your Internet provider, and on the contrary, it does not occur when connecting to another, call the provider's support service and follow the recommendations of the consultants.

No access to individual sites

The reasons

Lack of access to some sites can be caused by the bulk of the reasons listed above. But here there is one nuance - it is possible to make an assumption of the culprit of a failure on the subject of inaccessible content.

For example:

There is no access to torrent trackers and other similar resources prohibited in the territory of your country. Cause - blocking by a provider or a higher controlling organization. According to the rules, the plug-plug must open instead with a formid test " The site is blocked by decision ...", But sometimes an error appears" Unable to establish a connection with the site" By the way, sometimes under the distribution there are no no obey resources, such as Google services.
Do not open the pages of adult topics, VK and your favorite online game. Probable reason - Blocking with the means of parental control, firewall or DNS with the content filtering function. Sometimes in such cases, more sophisticated methods are applied - blocking through hosts file And so on what I will tell on.
Social networks, postal and antivirus resources, search engines do not open. This picture is characteristic of viral infection.

What to do

In the event of the unavailability of individual sites, the same methods of diagnostics and solutions that use with access to everything problems are used. But with the amendment: - Your allies, not enemies.

And separately about blocking methods that use malicious programs. To unlock access to the site, one removal of malware is often not enough: with it, it is necessary to remove the changes that it introduced into the system.

Hosts file

If it is simple, then the file % Windir% \\ System32 \\ Drivers \\ ETC \\ HOSTS - This is a local DNS service. It serves to specify a computer, which IP addresses to search for specific sites whose names are listed in this file. If you write to Hosts that ABC.com's website is located at 127.0.0.1, then the computer will look for it not on the Internet, but on your disks. And since it will not find - it will not be able to open in the browser.

By the way, viruses sometimes hide the recording from users that they contributed to Hosts. About concealment methods.

Hosts is a text file without expansion. To remove the locking record, open it in a notepad or replacing a notepad program and simply delete unnecessary lines. If after editing the file will be saved with extension.txt, delete the extension.

There is a class of malicious programs that can overwrite the DNS addresses in network settings PC and router. If you notice unfamiliar DNS on your devices, write the address of the provider or public instead of them.

Static routes

Static (permanent) Route is a rigidly prescribed path of web traffic from one network node (for example, your computer) to another (website on the Internet). Accordingly, if the route is specified incorrectly, the site will not appear. In more detail, this mechanism is described in the above.

To find out if there are permanent routes on your PC, run the instruction in the command prompt rOUTE PRINT.

To delete all routes, complete the following instructions: route -f.

Assigned tasks

The assigned task is some instruction that operating system performs on a schedule or upon the occurrence of some event (for example, after windows downloads). Such tasks can also create users (through the task scheduler), and the programs installed on the PC.

Assigned tasks are stored in folders % Windir% \\ Tasks and % Windir% \\ System32 \\ Tasksin the form of text files: one task is one file. A file created by a malicious program is usually easy to determine by a meaningless name made up from a set of numbers and letters, like sgjed4jlui.job. In addition, the date of its creation, as a rule, coincides with the date of occurrence of the problem with the opening of sites.

Before removing suspicious tasks, it is advisable to create them backups - In case of a possible error.

Malicious proxy

Proxy servers are intermediate nodes that pass through themselves network traffic (router) before entering the worldwide web and back. In addition to useful tasks, such as protecting the traffic or IP masking, they can be used by intruders to redirect the user's infected machine to phishing web pages, as well as to block access to individual sites.
