I have a project running UE4.19 with Blueprints (primarily) and C++ (for Discord RPC). In my blueprints, I try to join a Steam session. When I Play In Editor (Standalone) or package it and run it twice, I can host a Steam session from one instance and join it from the other. However, when I package it and play it from two computers, I can find the other session, but joining it doesn’t work. Why might this be?
