join session node fails after sending a invite though steam

hey everyone, new when it comes to doing multiplayer game, I have been trying to create a peer to peer 2 player online game, like A way out and portal 2, using the AdvancedSessions, and I can send invites to my friends but on the join session node it’s kept failing to join my friend lobby but finds the unique net id.

am not sure why that’s happening, i have setting up the blueprint inside the advanced friends game instance. any help would much appreciated :slight_smile:

Same issue. Just reloads the default map after a few seconds. :frowning:
