For more than several hours me and a friend try so setup multiplayer session, but we cant connect to each other.
I have the Steam Version, he has the GOG Version. Both are von 3.6.69.4648.
We always get the error "Connection failed: No free Slots".
When a third friend who has the game (Steam Version) sets up a lobby can both join it and start the game.
Anybody has an idea how to get this working?
