You can't join LAN Session using steam subsystem in 4.10.1
I tryed Multiplayer Shootout, in UE 4.10 You can't join LAN Session, but it perfectly works in UE 4.9
I also tryed to switch from steam subsystem to null and it worked fine (UE 4.10.1)
On UE 4.10.1 there is also another wierd bug,
After calling this event I'm transfered to Map_02 and in the next frame I get back to previous map (that also happens only on steam subsystem)
English is not my native language, hope You'll understand the problem.

Actually in our Project (Steamworks v135 & UE 4.10.1) we have the same problem with the OnlineSubsystemSteam and LAN Games. With the integration of Steamworks, the game is unable to find Listen Server across the LAN, both Standalone Game mode (PIE) and Packaged Game.
I wonder if there is information on this subject.
Thanks in advance for your attention!

Glad the map situation isn't occurring for you anymore. Please let us know if the problem starts happening again.
I have not been able to confirm whether the change to make multiple game instances on the same machine unable to connect was intentional, so I've entered a bug report for it (UE-24894). It appears this was fine in 4.10.0, so if absolutely necessary to test on one machine, you should be able to grab the 4.10.0 version from GitHub and build it from source. Otherwise, testing on separate machines should work fine.

The problem of going back to the previous map is because the GameName on your DefaultEngine.ini has to be the same as your project, else Steam will reject your connection, even after session was successfuly created.
