I am running Red Alert 3 on EA Games (I think the friend's copy is Ultimate collection on EA Games) hooked with C&C Online. I am able to log in and invite my friend to games, both multiplayer or co-op, but on attempting to start, I get the error message:
Connections are in progress, or connection problems detected. Please wait for the connections to finish, or kick the player who has the connection problem. Failed connections: 1-2
I am on Windows 11, he is windows 10, we are both in the same building if that matters. No VPN, disabled antivirus and its firewall.
