We all know that there are such situations: In a battle, or while joining a server, a message pops up: "Connection closed by server."

Ways to resolve this issue:

1) If an error pops up regularly, then change your password and mail (Explaination), probably this comes, because someone else is logging on into your account.
2) Your account could have been blocked by violating the rules (Cheating, hacking or sharing of your account). If your account get blocked, please contact help@tankionline.com
3) Clean the Flash Player Cache: How do I clean my Flash Cache?
4) Change your browser. The browser can be downloaded at the official site. Some browsers: Google Chrome, Opera, Firefox, Maxthon or Safari.
5) Update your Flash Player.
6) Remove your downloads, which you've made by using torrent, limewire, etc.
7) Maybe your computer was infected with a virus, try to delete the virus with the anti-virus program.
8 ) Check the connection to your Internet. Perhaps there are problems with your Internet provider? At this time the response from the server will be discontinued, since the session is terminated.
9) Slow internet. Check the speed of the Internet: www.speedtest.net. If the download speed is less, the files will load slowly. Recommended minimum 256/256 kilobits per second.
10) Clean up your browser's cache. (How do I clear my browser cache?
11) This problem may not work for the life of the scripts. To disable these scripts, first for the Firefox browser do the following steps:
A. Tools-> Add-ons, or key combination Ctrl + Shift + A.
Two. Looking for writing NoScript (read details http://ru.wikipedia.org/wiki/NoScript) and set this add-on.
Three. After restarting Firefox, below the button to appear: "Setup ...".
B. Select only the "Allow tankionline.com"
Note: If you come across other sites through the browser Firefox, you will need a button NoScript "Configure ...", give permission to a site that you want to attend. Do not click "Enable Java Script all" (very dangerous!).
12) Update your IP-address

I hope this guide will help you solve the problem of "Connection closed by server".
