Having searched the web up and down without getting definitive clues, there is nothing left but asking for help.
Problem: Steam-Lobbies created with my Unreal Game are not listed to other game clients.
-
I have tested with a game client on a different machine and different steam account. The problem exists for both clients in the same network aswell as in separate networks.
-
In all cases the steam download
server were the same for both server
and client. -
In all of these cases the
server/client were in a NAT-Network,
if that matters. -
The game is registered (not yet released) on Steam and uses an own App-ID. The App-ID is referenced within the DefaultEngine.ini aswell as the game_target.cs, as described in the numerous instructions.
-
The Steam-Overlay itself works and I can successfully retrieve the Steam Username.
-
The Game is packaged with the ProjectLauncher (currently in Debug mode).
-
