Steam Subsystem UE 5.7.1

Hey all,

Just wondering if anyone has had issues with connecting to a listen server via steam with 5.7.1? In previous projects I’ve set up Steam Subsystem quite easily in both c++ and blueprints. I’ve also implemented it with Advanced Sessions in blueprints and the change was very simple to implement.

However, for some reason 5.7.1 simply will not allow a user to connect to a listen server. The level simply reloads and sessions are no longer found. It works fine on lan, and when I load the game I’m loading “Spacewars” (as expected), but the second I use a second steam account on another computer, it either doesn’t find a server… or when it does, the previously mentioned behavior happens.

I’ve been working on this now for a week, when previously it took 15-20 minutes to get working. I’m at a complete loss. I’ve even set up new blank projects, with simple UI which loads a blank map and the same behavior happens.

Any information would be helpful.

Thank you
