I’ve setup my project, currently to use the Online Session subsystem NULL; just testing local online sessions until the project is further in development. This was working on UE 5.1 and since I’ve moved up to 5.2 now when attempting to join the session it times out.
I’ve tried launching game instances outside of the editor (so not in PIE) and packaging a build to put on a second PC and whenever I attempt to join the joining session stalls out for a bit then resets. In the logs I’m seeing that the connection timed out but I’m not seeing any errors as to why. I’ve checked my firewall settings for the .exe and they are set to allow traffic for my network.
Has anyone else run into this? Or can anyone see an error I might be missing?
Here are the relevant lines from the log (the logtemp are print statements I’ve added to understand when things were happening):
