Advanced Sessions Plugin

I am trying to find out if I missed something.

I am currently using Cardinal’s excellent menu to experiment with a multiplayer and lobby system.
I can start a host lobby and another player can log into that lobby. Using Steam and using LAN.
And I have read a lot of info and I know/understand that when using steam, I have to run a standalone session to make it work.
However, for now, and during testing, I am perfectly happy using LAN and PIE. And when I run LAN, and in PIE, the everything seems to work well, except for the “Get Session Info” node.
This node always fails getting the info in PIE+LAN. It works for StandAlone+LAN. I even reverted the OnlineSubsystem back to Null and used
“-NetDriverDefinitions=(DefName=“GameNetDriver”,DriverClassName=”/Script/OnlineSubsystemUtils.IpNetDriver",DriverClassNameFallback="/Script/OnlineSubsystemUtils.IpNetDriver")" and disabled the steam plugin.
However, the “Get Session Info” node always fails in PIE. This is unexpected for LAN. Am I missing something?
(using 4.15 and 4.15.1, same results)
