Fail to find more then 23 server if you "idle" for 90 seconds or more in the servers list, or if you refresh the list more then 5 times or if you get kicked from a server due to server rebooting.
Closing the game will not solve it. You can't join ANY of the servers on the list, they will all "Connection Timed Out!" Restarting PC, Rebooting Modem/Router, Switching to another connection will NOT fix it. Not an issue with locality. Friends from UK, Turkey, Ukrain, Germany, Hungary, Italy all have this randomly happening to them. Often you have to wait 45 minutes - 2 hours before you are allowed to play multiplayer again.
Multiplayer works fine on other games while this is not responding at all.
Other games that were working fine: Ark, Space Engineers, Empyrion, Minecraft, Borderlands 1 2 Presequel 3, Path of Exile, Trackmania, HL2DM, Portal2 and many more.
Even if I fully disable firewall it doesn't work!
