Warning: OSS: No game present to leave for session (GameSession)

Development Programming & Scripting Blueprint

Hey guys

I am learning networking with Unreal engine and I am getting error “Warning: OSS: No game present to leave for session (GameSession)”.

I tried to google this issue but couldn’t find any solution.

Have you got any idea or know any tutorials which show how to solve out this issue?

I have attached screenshot of the server log and the steps how to reproduce problem.

Thanks

How to reproduce this problem:

  1. Create new third person example project (Blueprint or C++ both print same warning into server console)
  2. Set number of player 2 or higher
  3. Net Mode: Play As Client
  4. Play as Standalone Game
  5. Check the server console

Yeah I came here looking for the same thing.

It looks like it comes from FOnlineSession classes, part of the “OnlineSubsystem” Plugin and is shown when the Online Session is null - which I guess by default it is (?). I’m not sure what the OnlineSubsystem plugin is for exactly, but this warning looks harmless.

Were you able to solve this?
