Hello everyone,
I’ve got a problem: when I’m trying to join a game, by using the Steam Advanced Sessions plugin, I can find the session but not join it 
.
To give you more context, I’m working on a multiplayer game, and I’ve made a demo build for testing (I add the plugins “AdvancedSessions” and “AdvancedSteamSessions” + edit DefaultEngine.ini).
In my menu, I’ve got 3 buttons:
• Create session
• Create a Lan session
• Search session (create a widget with the server name, current player, and a join button if it finds a session)
Everything works just fine inside Unreal Engine, but not with a build.
I’m testing on two different PCs (same wifi) with two different Steam accounts. The Lan session cannot be found, but the other one can.
I can see the session but can’t join it (the server name is empty, that’s weird).
I search in the log of the build and found these lines :

Does anyone faced this problem before and managed to solve it ?
Thanks a lot for all the people that could help or share they experiences about this problem, it would help me a lot to test with some friends my game.
Good day everyone
