[Describe the bug here]
So I’ve been having a problem. Me and my friend are not able to play coop together. It says we’re losing convection to the host. If I host, he can’t connect. If he is hosting, I can’t connect. It worked fine about a month ago. We pretty much tried everything that we found here in the forums. Someone please help us
