When the dedicated server initializes, it loads a large map and I believe it’s timing out at 15 seconds due to the log entry below. No reason for the failure, but it ALWAYS happens at 15.0x seconds. Smaller maps load and initialize just fine.
As a test I run the game server software on my dev machine which is beefier and the game loads just fine in about 9 seconds. I really think this is an async timeout.

The call to create the session is here:
void UNoNameGameInstance::CreateDedicatedSession()
{
SessionInterface->OnCreateSessionCompleteDelegates.AddUObject(this, &UNoNameGameInstance::OnCreateSessionComplete);
LastSessionSettings = MakeShareable(new FOnlineSessionSettings());
LastSessionSettings->NumPrivateConnections = 0;
LastSessionSettings->NumPublicConnections = 5;
LastSessionSettings->bShouldAdvertise = true;
LastSessionSettings->bAllowJoinInProgress = true;
LastSessionSettings->bIsLANMatch = false;
LastSessionSettings->bIsDedicated = true;
LastSessionSettings->bUsesStats = false;
LastSessionSettings->bAllowInvites = true;
LastSessionSettings->bUsesPresence = false;
LastSessionSettings->bAllowJoinViaPresence = true;
LastSessionSettings->bAllowJoinViaPresenceFriendsOnly = false;
LastSessionSettings->bAntiCheatProtected = false;
LastSessionSettings->bUseLobbiesIfAvailable = false;
LastSessionSettings->bUseLobbiesVoiceChatIfAvailable = false;
LastSessionSettings->Set(SETTING_MAPNAME, FString("BlueSkyMap"), EOnlineDataAdvertisementType::ViaOnlineService);
// I believe the timeout is happing on this call
SessionInterface->CreateSession(0, FName("NoNameGameSession"), *LastSessionSettings);
}
Although I think this is a timeout, how can I find out for sure. There seems to be no way to get the reason for the failure.
