nevermind, i just tested it and it is problem with downloading the map, idk why, i must figure it out asap. Thx for help anyway :)

srry my bad, i'll put password on it: 1234

I just tried again : Server Full, 2 players on it!

Thx for respond, it seems like issue only when you try to coonnect on some cusom map which is externally hosten on my Google drive for faster upload speed.

I need from you some testing if you don't mind: Start the game, open client console window by hitting the "~" key (if it won't work, go to the options menu -> game settings -> console -> enable) and try connect to "Arc's TEST" server and if it kicks you out like before, the console will print some error message, like "map does not exist" or "unable to find map" and something like that, i need from you to copy this message and post it here.

You will be really helpfull if you do this and i thank you anyway :)

Hello Arc, I tried to go on this server... it sends me every time on main menu !
(sorry for my english !)

Ohai, did you tried [CZ] Arc's v1.3.8.0 CooP server in Insurgency ?
I need to know if you disconnected by yourself or if the game just throwed you back to the main menu.
