You need to carefully read the terms of completing the mission. Perhaps not all conditions were met. For example, you might have chosen the wrong game mode or you didn’t go to the “Missions” screen before completing conditions.

If the error appears in the screen almost immediately after entering the game, it is possible that someone else is logging into your account. Change your password and email. If you cannot access your account, contact technical support.

Other solutions:

1. Use the game client. You may download it on the main page.
2. Try using another browser. Browsers can be downloaded from official sites – Chrome, Firefox, Opera, or Opera GX.
3. Perhaps your internet connection is too slow. Try to reset your Internet connection (turn your router off and on again), and stop all downloads.
4. Clear cache of your browser or client.
5. Try using these instructions on how to speed up game loading.

The problem with lags usually occurs due to poor connection on your side and/or on the side of other players — delays or packet loss on the way to the game server and back. Symptoms may include high ping, delayed screen updates, and passing through other tanks. To understand where the problem is coming from and what it is about, it is worth diagnosing your connection to the server.

Sometimes there may be delays when opening the garage, friends list, or battle list. This is usually caused by heavy server load (usually during events), technical work on certain servers, problems in data center, or global internet problems.

You can try to solve the problem of long loading times by clearing cache of your browser or client. Tanks Online caches game resources on your computer and automatically updates them if necessary. In some cases, old versions of resources can conflict with new ones and with the game server. A hidden error occurs, and the game cannot load.

If the game takes a long time to load every time, perhaps the browser clears the cache automatically when closed or the temporary files storage time is set too small. Check your browser settings. Background programs such as Skype, Discord, file downloaders (Torrent, Download Master), etc., affect the loading speed. It is better to avoid using them while playing.

If you tried everything described above but the game still takes a long time to load:

1. First, check your internet connection. There may be problems with your ISP.
2. Try disconnecting the modem from the network for 15 seconds and then reconnecting it.
3. Packet loss may occur on the route to the game servers. To check:

• Press the Win+R key combination, type ping c1.eu.tankionline.com -t in the window that appears, and press OK or Enter;
• Wait 10–15 seconds;
• Press the Win+R key combination, in the window that appears, type ping c1.eu.tankionline.com -t and press OK or Enter;
• Wait 10-15 seconds;
• Press Ctrl+Break, statistics will be displayed:

If the value of packet loss is more than 0, check the cables and router/modem settings. If you cannot solve the problem yourself, contact your ISP about packet loss.

Possible reasons:

• Poor connection quality;
• Anti-cheat malfunction;
• Problems with the main channel;
• Issues with game servers.

Damage may also not be dealt to a player who has the «Invulnerability» status effect applied.

If you have any problems with being unable to appear on the map, pick up bonus boxes, deal zero damage, etc., first of all, refresh the browser page.

Other solutions:

• Clear cache of your browser or client.
• Try playing through another browser or the official game client.
• Diagnose your connection to the server.

No Sound

First of all, you need to check the volume slider in the game settings.

If sound is enabled in the game settings, the problem may be with the audio device on your computer. open the sound manager on your PC or laptop (usually, it looks like a dynamic or a speaker in the taskbar near the time/date), move up the sliders, and check the sound again. Make sure that the main (first) slider is not at the very bottom. Also, check the browser’s or game client’s slider.

If you are playing in a browser, check if the sound for the game tab is on. To do this, right-click on the tab.

If the sound doesn’t work while playing on TO Mobile, check the volume settings on your device. Also the sound may be forcefully turned off on your device – developers know about this problem and are trying to solve it.

TAB or Delete Doesn’t Work

If the TAB key doesn’t work, pressing the ESC key twice usually helps. Also you can just press P, wait for the menu with PAUSE to appear, and then close it.

Also check if tank controls aren’t changed.

In order to solve the issue with “Lost server connection”, click on the respective section and follow the instructions.

An error in the battle most often means that either some resources were loaded incorrectly, or the loading takes too long and therefore it was interrupted, or the download cannot be completed because the hardware on the user’s device is too weak. You can read more about the game’s specifications here.

How to reduce the likelihood of an error in battle?

• Refresh the page after a couple of battles.
• Lower the graphics settings in the game settings.
• Disable additional programs that affect computer performance or use a large amount of traffic.
• Reduce screen resolution.

WinMTR (Network Diagnostic Tool)

Windows:

Download, unzip and run WinMTR.

In the “Host” text box, enter the name of one of the servers in the form c[server number here].tankionline.com; for example, the name of the fifth server will look like c5.tankionline.com.

Press the “Start” button, and then let the program work by itself for at least 10 minutes, though preferably for half an hour. It is desirable at this time, to try to play, to ensure that you catch all statistical problems at first.

To complete the collection of statistics, click “Stop”. To insert it into the forum, copy the result to the clipboard button, which reads “Copy text to the clipboard”; then, paste the data into a text message (it is also ideal to frame the tag [code=auto:0] .. [/ code], to give it a table viewing format).

Linux:

Linux users can use WinMTR, which should already be in the computer system. Recommendations for choosing a server name, and the statistic collection process, is the same as for the users of Windows operating systems.

Other Network Scanners (Mac)

Mac OS X users are not able to use WinMTR and thus need to run alternative programs on their device.

Result interpretation

If you post a new topic with the information, make sure to do so in the “Problems and Solutions” forum, it’s the best place to put your results. Among the participants of the project, there are competent people, who are willing to help in such matters. If you want to analyze the results yourself, then first of all look at the last line of the route (this is actually a game server) loss (column “Loss%”); this stage reading should not exceed 1.2%, the average round-trip times (“Avrg”) should no greater than 200 ms, and the maximum (“Worst”) – no more than 500 milliseconds. An ideal variant: Zero losses, with an average ping not exceeding 100 ms, and the minimum (“Best”) and maximum (“Worst”) do not vary from the mean by more than 50%. In the presence of an abnormally large loss or number of pings, look back to a better-scoring test, and note the differences you see there.

Command Prompt

Testing Ping:

“Ping” – the time it takes to transmit a packet of information in a computer network from the client to a server and back from the server to the client.

Ping is the most important characteristic of server connections. It determines how quickly you will receive current information about the whereabouts and actions of other players, and how quickly you send your actions to the server. High and unstable pings often cause lags – long delays in data transmission.

Ping can be checked by using the standard Windows operating system. To do this, run the console (command line) Windows, and the cause of its command ping. You can run a command line in a few different ways. One of them is to click on the Start button, select from the menu “All Programs,” and in it – see “Accessories”. In the list of standard programs will be “Command Prompt.” Another way – again, click on the Start button, select the Run menu in the window that opens, and in the line “Open,” write ‘ cmd ’ and click OK. And finally, the easiest way – to use the key combination Win + R. At the command prompt, type the following command ping followed by a space for the server address.

For example, a ping test for the fifth server will look like this: ping c5.tankionline.com. Press the Enter key and monitor the results.

Result interpretation

When you ping-test a server, here are what your results will generally look like;

• size of an outgoing packet in bytes (default – 32 bytes);
• response time in milliseconds;
• TTL (time to live) – the time that the computer will wait for a response from the server.

By default, the four packets are sent to the server, then the test results are displayed;

• total number of transmitted packets;
• number of packets received;
• number of lost packets;
• percentage of data lossage( degradation);
• maximum, minimum and average round-trip time of the package.

If you did not receive all the packages after sending them, or the spread between the maximum and minimum time of file handover was too large, it may be a sign of problems with the network.

Sometimes, problems with passing packets (especially large ones) are automatic anti-viruses or firewalls, so before checking everything, it’s best to disable ping on their interface controls.

Ping between 0 & 100 and filespeed spread in the range of 20% (of each other) are considered normal.

Tracing Route

Sometimes it is necessary to know the route that game traffic passes through, from you to the servers. It is necessary to identify problematic areas on this route, in the event of massive problems in one or another parts of the user/client.

You can do this using a utility tracert (Windows) or traceroute (for Linux). Program tracert, as the program ping, runs from the command line interface. Click on the “Start” button, select the item “All Programs” (or “Programs,” for earlier versions of the operating system) in it – see “Accessories”- in the standard programs list, click on the item “Command Prompt.” Or click on the “Start” button, select the item “Run” in the “Open” window, and write cmd and press the OK button, or press Enter. You can also use the key combination Win + R. In the window that opens, type in the cmdlet tracert c5.tankionline.com (it will trace to the fifth server) and press the Enter key. Enter the address.

We thus have established a route to the end node. In the Command Prompt window, in the real-time trace output, put the name and IP address of the intermediate nodes, and the response time will be shown in milliseconds.

Result interpretation

In the portions of the route where the response time is minimal, the transmission is carried out most quickly. This means that the channel is not overloaded, and is, substantially, without any noteworthy interference.

However, where the response time is more than the standard amount, we get the result of a “request time out,” which is equivalent to the loss of data packets.

Thusly, it is possible to determine where in the chain the problem is. If packets do not reach the destination – it is a problem within it. If the chain breaks off in the middle, there is a problem in some of the intermediate routers. At the same time, on another computer, or on a different route (if it exists), the site can be accessed. If the packages exceed your ISP’s network, then there’s the problem.

Please post your statistics in a topic, or contact a moderator so we may be able to analyze them and find the solution that suits you the best.

Sooner or later some players may encounter a problem that they either can’t shoot while turning or turn while shooting.

There are several methods of solving this problem.

If you have *unix systems (for example Mac OS, Linux, etc.) and can’t rotate the turret – change your keyboard layout.

Mouse Controls

Mouse controls were introduced to the game on April 8th, 2015. Mouse controls are activated by selecting the respective option in the Settings menu. The cursor can be shown by holding the TAB key.

If you don’t want to use mouse control, turn off this option in the Settings. The turret (especially on hover tanks) may not rotate because of this.

Transition to WASD

The turret can be turned with the <, >, and ? keys.

That, most probably, will make almost all button combinations be processed correctly.

As an option, NUMPAD (number pad) can be used. This way, controls will be responsive to the 2, 4, 6, and 8 keys. The reverse button will be further than on the arrow controls Most players are already used to playing on arrow controls, so this option is often uncomfortable for them.

Changing Controls in Game

Almost all tank control keys can be changed in settings. Try out different combinations and find the layout that is processed correctly and is comfortable to play with.

One possible option is to set the tank direction controls (by default the up, down, left, and right arrows) to the number keyboard (1, 2, 3, 5), shown at the right. Camera controls could be set to 4 and 6.

Buying a New Keyboard

Expensive gaming and office models usually process these combinations well. Any keyboard should be tested before purchasing, for example with this testing website. Try to press different keys to see if there are combinations that aren’t processed correctly.

Playing with two keyboards simultaneously

Extreme but working option: connect two keyboards to your computer and press some keys on one keyboard and others on the second one.
