Tried running a Co-op campaign with my brother who lives a few towns over but we got this error:
Connections are still in progress or connection problem detected, please wait for the connection to finish or kick the player who has the connection problem.
Failed Connection: 1-2
When either of us tried to start the actual campaign or skirmish maps.
I run windows 10 and he runs windows 7 if that is any help. We both run the steam version.
We both tried all the solutions on the common issues and solutions board without any change.
Haven't tried to connect to anyone else yet.
