I bought 2 copies of this game to play cooperatively on LAN and it does not let me,
When creating the cooperative game and inviting another player over LAN, the following message appears to the other player:
The player is not playing on any game server.
What is the problem?
The ports are open, firewall disabled.
Hey there! It’s a known issue and one I run into sometimes. I’ve gotten around it by completely closing Discord. Do you have it open? If so, close it and make sure it’s not running in the background. Open and start your singleplayer game, then invite your friend. That should work and you can open Discord again.
