Many people I see are having issues with creating and inviting people to join a co-op game. This kind of smells like a port problem, with the default seemingly being 27015 set when creating the game. Forwarding that port doesn’t seem to help with the issue, does anyone know what port to forward on routers to allow for co-op play? Or how to solve the issue of not being able to join a game that you’ve been invited to?
Dedicated look to be working but haven’t had a chance to try and join one.
