This is for Red Alert 3, I forgot to mention that in the subject.
I constantly get this error when I start a game.
I create a lobby, my friend tries to join, "Host has left the game"
He creates a lobby instead and I try to join, "Host has left the game"
I tried letting everything through my firewall, but nothing helps.
Edit: When I start a co-op game, the same issue occurs both ways.
I can join other people completely fine.
