I cannot get my dedicated servers to show up on the steam server browser. Not in steam, not in-game. I can connect to the server via steam ids. Here are some logs from my server:

One curious thing in the logs during shutdown:

[2023.08.23-17.22.58:596][984]LogOnline: STEAM: Removing P2P Session Id: UNKNOWN [0x1100001071C76CF], Channel: 7777, IdleTime: 0.035

Unknown session id?

My code for RegisterServer (it hits the logs so it works):

void AClaymoreGameSession::RegisterServer()
{
	Super::RegisterServer();

	if (IsRunningDedicatedServer())
	{
		// Register Server with Steam
		UE_LOG(LogTemp, Warning, TEXT("Trying to register Steam Server Session."));
		IOnlineSessionPtr SessionInterface = Online::GetSessionInterface();
		if (SessionInterface.IsValid())
		{
			FOnlineSessionSettings Settings;
			Settings.NumPublicConnections = 100;
			Settings.bShouldAdvertise = true;
			Settings.bAllowJoinInProgress = true;
			Settings.bIsLANMatch = false;
			Settings.bUsesPresence = false;
			Settings.bAllowJoinViaPresence = false;
			Settings.bIsDedicated = true;
			Settings.bAntiCheatProtected = true;
			SessionInterface->CreateSession(0, NAME_GameSession, Settings);
			UE_LOG(LogTemp, Warning, TEXT("Registered Steam Server Session in RegisterServer."));
		}
		else if (GetWorld()->GetAuthGameMode<AClaymoreGameMode>())
		{
			UE_LOG(LogTemp, Warning, TEXT("Failed to register Steam Server Session."));
		}
	}
}

and lastly my project settings:
