This happens due to instability of your internet connection. Reboot your modem and it will be fixed.

My connection is great . I use a gaming laptop 64gb ram and my wifi is 100mbps with a D-Link Gaming router . my internet service provider also supports this game no issues....

Same Problem with me :((
I have a great connection , i can play all other games including tanki x on the client . But i cant play tanki online on the client version i downloaded from Steam . it used to work for about a week and then it just stopped showing this error. EVERYONE is facing the same situation . Please Update the application .... ;((
