OnlineSessionSteam fails to find created game session

Hi,

I have implemented simple creation and searching for the sessions in Ue4, following all examples.
I’m using Steam.

I cannot find any session even though I:

  • use steam_appid.txt with the reasl appid received from steam
  • two steam clients on different comupters, set to the same download region
  • Using Presence when creating session
  • Not using LAN when creating or searching
  • the log entry are following:

LogOnlineSession: Verbose: STEAM: “gamedir” “unrealtest”
LogOnlineSession: Verbose: STEAM: Server query complete ‘2’ eNoServersListedOnMasterServer (No servers match)
LogOnline: Verbose: OSS: Async task ‘FOnlineAsyncTaskSteamFindServers bWasSuccessful: 1 Results: 0’ succeeded in 0.454612 seconds

(In my code if I find 0 sessions I automatically create a new one)
LogOnline: Verbose: OSS: Async task ‘FOnlineAsyncTaskSteamCreateLobby bWasSuccessful: 1 LobbyId: 109775244191529684 LobbyType: 2 Result: ‘1’ k_EResultOK (success)’ succeeded in 0.203882 seconds

What else could it be?

Thanks!
