Tanks do not connect to the server. Cannot establish a connection to the server in WoT

There are a lot of complaints from players about an error in connecting to World of Tanks. In this material we will tell you how to solve the problem with connecting three different ways and let's look at each in detail. The solution is suitable for those who receive the following error when connecting to tanks:

Cannot connect to server

The server may be unavailable or the settings need to be checked network connection.

Problem with connection in tanks

The player himself writes about this error following:

It also doesn’t connect to the test server, I play other games without any problems, I sit in the TS, I write on the forum, the updates to the test server have been downloaded and installed, but I can’t log into the game. There are no mods.

Solution

Option 1.

According to our data, this problem occurs among those players who use xDSL technology(ADSL 2+) and high-speed modem. Immediately after the previous patch, the World of Tanks server began cutting off tankers with an unstable network connection from the game. All cases spoke specifically about a modem connection, which, by the way, is high-speed and is not inferior in stability to ETTx and even xPON technology, if no more than 300 meters of copper pair are laid from the player’s computer to the PBX. However, ADSL is capable of providing Internet access over distances of several kilometers (here the connection quality drops sharply).

Solution for option 1. If you are using ADSL, try to consider alternative options Internet access using more stable technologies PON (optics to PC) or ETTH (optics to home with branching to users via RJ-45 twisted pair cable).

Option 2.

Of course network settings your his personal computer which is referred to in the error in connecting to tanks. This primarily includes setting up a router, NAT, giving connection permissions to the worldoftanks.exe file in firewalls and adding firewall exceptions. Also opening the ports used to connect to WOT.

Solution for option 2. Places to look to check your network connection settings if the server is unavailable include:

Settings of the used network card and adapter parameters (DNS, IP address, TCP/IP gateway).
Network connection settings. Namely: the shortcut through which you connect to the Internet (relevant for bridging connections); web interface of the router or modem at the address: http://192.168.1.1 with login admin and password admin(relevant for PPoE connections).
Firewall settings built into the antivirus. This is done through the antivirus management program. Add an exception to block connections to the World of Tanks server for the executable file of the same name with the .exe extension from the game folder.
Settings Windows Firewall. Here you should also allow establishing a connection to the World of Tanks server by adding an exception for the game.
Settings network groups(home, public and others).

Option 3

This is a rare but important situation that can cause an error in which a connection to the server cannot be established. This includes blocking a player's IP address on World server of Tanks you are trying to connect to. The MAC address (the hardware address that identifies the device on the network) may also be blocked.

Solution for option 3. We recommend that you change the one issued to you from your provider. static IP address. If you have dynamic IP address, just reconnect the Internet so that your IP address changes to a new one. In the case of blocking by MAC address, you will have to contact Wargaming with a request to unlock the MAC of your network card, modem or PC (unless, of course, you are going to change them or use another computer, modem, router and network card to connect to World of Tanks ).

"Cannot install network connection in WoT. The server may be unavailable or your network connection settings may need to be checked." Does this message sound familiar to you? Then this is the place for you. This message can occur for hundreds of reasons.

You must clearly understand the decoding of this message. Although there is nothing special to understand here. Tanks swear that you either do not have Internet, or the client for some reason cannot find a connection to game server. That is, you launched the client, which in turn tries to go online and search for its server at a pre-known IP address, but the server does not respond to it and accordingly an error message is displayed. Next, for clarity, let’s look at exactly how the procedure for connecting to the game server goes:

Game client on your PC(trying to connect to the server goes through) ->
windows firewall(if installed), if the firewall allows the connection, then ->
antivirus(if installed) asks the game client, “Where are you going? What if you’re somehow different” and if it gets the go-ahead from the antivirus, then ->
connection signal passes to your PC's network card ->
Further, router(hub, switch, router or whatever else you have) ->
then, provider(there is a mountain of equipment there, we won’t go into that) ->
and as a result myself game server.

Now, I hope, everyone understands the scheme by which it is necessary to find the problem that prevents the client from connecting to the server. Let's move on...

By the way, in more detail about the connection router -> provider -> game server I talked about it in the article “High ping in wot - there is a solution”, because... this equipment largely affects the “lags and freezes” in the game. If you are very high ping, then you are welcome to read it.

Can't establish a network connection in WoT

How are we going to fight?!
BUT, the very first step will be entering the wargaming portal itself dedicated to tanks. Welcome! What if some work is currently going on on the servers? The developers inform you about this in advance and even describe the time during which the servers will be unavailable, and they post all this on their website, so don’t be shy and go in.

Next we follow the “scheme”. After the game client, the first obstacle is the firewall. Disable it (instructions) and try to enter the game. Happened? Congratulations! Play with the firewall disabled or read the article below.

So, we have identified the culprit. Now you need to open the ports and create rules for this “naughty little girl” ( windows firewall). But first, let's do the same thing only in automatic mode.

Let's go download .bat file from wargaming server:

archive for Windows XP;
archive for Windows Vista, Windows 7, Windows 8, Windows 10;

It's not a virus, don't worry. You can open it with Notepad ++ and make sure. Here are its contents:

@ECHO OFF
set Arg1=»%~d0%~p0WorldOfTanks.exe»
set Arg2=»%~d0%~p0WoTLauncher.exe»
IF NOT EXIST %Arg2% GOTO errorwotl
netsh firewall add allowedprogram %Arg2% WoTLauncher enable all
netsh firewall add portopening udp 20010-20020,32800-32900,12000-29999,5060,5062,3478,3479,3432,30443,53,6881-7881,1900 wot-udp enable
netsh firewall add portopening tcp 80,443,5222,5223,6881-7881 wot-tcp enable
IF NOT EXIST %Arg1% GOTO errorwot
netsh firewall add allowedprogram %Arg1% WorldOfTanks enable all
chcp 1251 >NUL
set text_y="WorldOfTanks.exe" and "WoTLauncher.exe" were successfully added to the firewall exception list.
chcp 866 >NUL
echo %text_y%
GOTO exit
:errorwotl
chcp 1251 >NUL
set text=Failed to find file "WoTLauncher". Make sure the file is located in the game client folder.
chcp 866 >NUL
echo %text%
GOTO exit
:errorwot
chcp 1251 >NUL
set text_l="WoTLauncher" was successfully added to the firewall exception list. The file "WorldOfTanks.exe" could not be found. Make sure your game client is updated to the latest version.
chcp 866 >NUL
echo %text_l%
:exit
PAUSE

Now launch the game and try to connect to any server. So how? Works? We defeated the message “Unable to establish a network connection in WoT”, HURRAY! Let's go play and don't worry about anything else! If it doesn’t work, then we’ll go do everything manually.

In order for the message “Unable to establish a network connection in WoT” to no longer appear, it is necessary that some ports are open in the firewall for the launcher and the game client, here they are:

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

For work voice chat It is also necessary for WorldOfTanks.exe to open the UDP range from 12,000 to 29,999 and ports 5060, 5062, 3478, 3479, 3432, 30443.
For work text chat necessary for WorldOfTanks.exe to open TCP ports 5222 and 5223.

In addition, you can allow WorldOfTanks.exe to use the UDP protocol and the TCP protocol on any ports in both directions, thus allowing firewall allow the game client to pass any packets to any addresses.

For WOTLauncher.exe need to open:
-UDP ports 53, 6881, 1900.
-TCP ports 80, 443, 6881.

Instructions for setting up the Windows firewall.

Well, how did it work out? If YES, then I’m happy for you. Well, if not, then don’t despair and read on...

The next obstacle to connecting to the server is the antivirus. If you don’t have it, then skip this paragraph.
Try adding the game folder to the trusted zone of your antivirus. BUT before that, check your computer for viruses.
Everyone’s antivirus is different, which is why the development team wrote a whole book with instructions for you and me, the link to which I provide here. (Many thanks to them for their titanic work)
How to add a game client to the antivirus exclusion list.

You can also (but not necessarily) add a list of server IP addresses.

Servers RU1–RU9:
92.223.19.1 - 92.223.19.255
92.223.8.1 - 92.223.8.255
92.223.1.1 - 92.223.1.255
92.223.12.1 - 92.223.12.255
92.223.18.1 - 92.223.18.255
92.223.4.1 - 92.223.4.255
92.223.10.1 - 92.223.10.255
92.223.14.1 - 92.223.14.255
92.223.36.1 - 92.223.36.255
185.12.240.1 - 185.12.240.255
185.12.242.1 - 185.12.242.255
Range of addresses required for the launcher and portal to work:
185.12.241.1 - 185.12.241.255.
Ranges of server addresses required for voice communication:
64.94.253.1 - 64.94.253.255
74.201.99.1 - 74.201.99.255

In some cases, disabling the antivirus and firewall does not solve the problem - the ports remain closed.

Here either the network connection is faulty, or herself Windows already moves the horses By the way, this may cause lags and slowdowns in the game. A separate article has been written on how to deal with them. Now let's try to reset the TCP/IP network settings and all sockets from the command line Windows strings using the command "netsh winsock reset» .

Launch the command line:

– For Windows XP: Click Start > Run. In the window that opens, enter cmd.exe and click OK.

– For Windows Vista and Windows 7: click Start, enter cmd in the “Start Search” field, click right click mouse over the cmd.exe file and select “Run as administrator”.

– For Windows 8: on the desktop, press the key combination Win+X. In the menu that opens, select “Command Prompt (Administrator).”

Enter in command line team netsh winsock reset and press Enter.

Now all that remains is to restart the computer.

If a message appears on the screen while working with the program "Unable to establish a connection to the server.", follow these steps:

1. Check if your computer is infected with the Kido worm

Read the article about the symptoms of infection and methods of treatment How to fight the Net-Worm.Win32.Kido network worm.

2. Check Internet access

Check if it's available Internet by opening in the browser Internet Explorer website Kaspersky Lab. If access to Internet no, please contact your ISP to obtain additional information. Please try to activate the application again after you have restored access to Internet.

3. Configure Firewall correctly

If you have installed on your computer Firewall, then make sure that in the settings Firewall there is an allowing rule for the process avp.exe.

Firewall (firewall) designed to ensure the security of your work on local networks and the Internet. Firewall represents software package, which checks data transmitted over the Internet or local network, and, depending on the parameters Firewall(direction, transmission protocol, destination addresses and ports), blocks or allows this network activity.

4. Check the system date on your computer

How to check if it is installed correctly system date on your computer, you can find out from article KB3508.

5. Try activation again in an hour

6. Contact Kaspersky Lab Technical Support

If the error appears again, we recommend that you contact Technical Support. Kaspersky Lab by sending a request through the service My Kaspersky and describing the problem in detail.

There are a lot of complaints from players about an error in connecting to World of Tanks. In this material we will tell you how to solve the connection problem in three different ways and will dwell on each in detail. The solution is suitable for those who receive the following error when connecting to tanks:

Option 3

This is a rare but important situation that can cause an error in which a connection to the server cannot be established. This includes blocking the IP address of the player on the World of Tanks server you are trying to connect to. The MAC address (the hardware address that identifies the device on the network) may also be blocked.

Solution for option 3. We recommend changing the static IP address assigned to you from your provider. If you have a dynamic IP address, all you need to do is reconnect the Internet for your IP address to change to a new one. In the case of blocking by MAC address, you will have to contact Wargaming with a request to unlock the MAC of your network card, modem or PC (unless, of course, you are going to change them or use another computer, modem, router and network card to connect to World of Tanks ).
