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

Development Programming & Scripting C++

I’m getting a bunch of errors in my log and it’s stopping anything from happening ingame… This is from joining with 2 players and a dedicated server with PIE.

Anyone got any ideas? I swear it wasn’t doing this before :frowning:

Is the project itself just corrupt? I feel like I should just transfer everything over to a fresh one at this point :frowning:

No need to clear anything. PIE has many restrictions when testing network/sessions, you should create two bat files, one for a server and one for a client and start them separatly.

I just recently went to 4.26.1 and I am now seeing these errors. However, I am running just fine. I am doing the same as you except for 3 players. I have overridden RestartPlayer in my subclassed GameMode recently and was thinking that was the trigger for these errors, but seeing your report I am not leaning that way now.

I searched the engine for “No game present to join for session” and it comes from listing below. Nothing I am explicitly using.

I would focus on your “No owning connection errors”.

This warnig is generated when you join an EOS session without overriding the variable ‘FName SessionName’ of the class AGameSession. so when the function RegisterPlayer is called after a Join, the parameter SessionName passed by the class to this function is None and so this function return a non success state. make sure to override the variable value before calling join function. here an example:
In RegisterPlayer override function

// Override RegisterPlayer function
void AEOSgameSession::RegisterPlayer(APlayerController* NewPlayer, const FUniqueNetIdRepl& UniqueId, bool bWasFromInvite)
{
	
	Super::RegisterPlayer(NewPlayer, UniqueId, bWasFromInvite);
	SessionName =aSessionName; // override SessionName value
       .
       .
       //... your logic when a player registered...
}
