Hey everyone! I’ve finally reached the build stage of my multiplayer game to do my first tests with friends. I was so excited, despite a few small issues (like needing to create a C++ class because UE4 requires it, or Steam not launching because I had to create a Steam_appid file with the code 480 inside).
I’m unable to see my friends’ sessions or join them. What could be causing this? The session creation, or session search? Note that the find Advanced Session node returns “0 servers found,” even though everything works correctly in the editor (and Steam does launch in the build).
You can imagine the little disappointment of not being able to finally test it 
. Any help would be greatly appreciated, and I thank you for any attempts to assist!
