On the client machine you click join and it finds the session ok, and tries to join it.
The log says…

Ok, we were missing in our DefaultEngine.ini the line
[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")
Debugging further…

It says solved, but it doesn’t seem like it, were you only missing that line in the engine.ini?
