CreateSession - Invalid player state

Hi all,

I am attempting to use the Create Session node inside my level blueprints. On begin play I check that the program is a dedicated server, then I delay 1 second, then attempt to create the session with 3 public connections and UseLAN set to true. However when I run it get the error the Script Msg: CreateSession - Invalid player state, this happens both when I run the program from the editor using the -server -log options and in a packaged server build.

Although I am using a custom gamemode in c++ inherited from AGameModeBase the blueprint gamemode that inherits from my c++ gamemode has the default PlayerState selected for “Player State Class”.

The correct modules ( "OnlineSubsystem", "OnlineSubsystemNull", "OnlineSubsystemUtils" ) have been added to my Build.cs file and


has been added to my DefaultEngine.ini file.

Any ideas what might be going on?
