Edit: I was able to get it working. Here’s my post in another thread. Hope it helps
I don’t have any fix, but I’m also having this issue. I’ve just started using Unreal and was really excited to get steam up and running. I wanted to test with friends but cannot get anything to connect.
For me, the session gets created just fine, my host loads into the game level but it’s in Standalone mode, not listen. My client can see the session and gets all the way through to the join but doesn’t move to the game map, probably due to the lack of the host listening.
