Just tried to start the game and getting the error saying that the game server is not reachable, I have checked the internet connection and this is ok. Is anyone else having this issue or found a way of fixing it. Thanks
Switch to a different language in the game properties on Steam client and then switch back to English. In my case this fixed the problem with the server connection.
Try to open properties, change language to Polish and close properties. Now run the game, go to the menu and exit. Open properties again and switch to English.
