When I join any game on Polytoria, there is a see through window that pops up and closes after 1 second. It does not join the game and is really annoying! My firewall is disabled and I do not know what to do. I have tried reinstall it many times but the same thing always happens.

I am on Linux Mint 20 and I installed the Linux client!

Please help.

Is client down or smt? What device do you even need to play the actual game?
