Problem on Creating/Finding Session using the Steam OSS

[ElohGD]

Hello everyone!
I spent the last couple of days trying to setup the creation and the finding of a session with no luck.
Current setup:

• Unreal Engine 5.3
• Host: My own PC
• Client: My SteamDeck with another Steam Account

DefaultEngine.ini:
___________________
// Other configs
...

[/Script/Engine.GameEngine]
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemSteam.SteamNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystem]
DefaultPlatformService=Steam

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=<my_app_id>
bInitServerOnClient=true   // This will use Steam game servers instead of lobby

[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"

After hours of testing, I found something really odd.
Even if I set bIsLANMatch = false (in create session settings), in the game server list (under LAN section) my session shows up and I’m able to find my session if I use “sessionSearch->bIsLanQuery = true;”
If I set bIsLANMatch = true (in create session settings), in the game server list my session doesn’t show up and I’m not able to find my session if I use “sessionSearch->bIsLanQuery = true;”
(Nope, I didn’t mess with writing down the boolean flags, this is how it works on my pc aha)

Of course this is not a suitable solution for possible release of a game.
From my understanding, to rely on Session, I should use this configuration:

Host() {
    if (sessionInterface.IsValid()) {
		FOnlineSessionSettings sessionSettings = FOnlineSessionSettings();
		sessionSettings.bIsLANMatch = false;
		sessionSettings.NumPublicConnections = 2;
		sessionSettings.bShouldAdvertise = true; 

		sessionInterface->CreateSession(0, SESSION_NAME, sessionSettings);
	}
}

____

FindSessions() {
    TSharedPtr<FOnlineSessionSearch>sessionSearch = MakeShareable(new FOnlineSessionSearch);
	
    sessionSearch->bIsLanQuery = false;
	sessionSearch->MaxSearchResults = 20;
	if (sessionInterface) {
		sessionInterface->FindSessions(0, sessionSearch.ToSharedRef());
	}
}

From my understanding I should use “sessionSettings.bUseLobbiesIfAvailable” and “sessionSettings.bUsesPresence” only on Lobbies, that’s why I’m not using this.
The last part of the code I would say it’s higly important to understand the code, is the callback for my CreateSession:

	if (successful) {
		findSession(); // I added this just for debug, to see if Im able to find my session after creation
		GetWorld()->ServerTravel("Path/To/Map?listen");
	} else {
		// Print failure to create session
	}

The last part I’d like to share is this:

• I create a session
• I try to look for my session
• With “FNamedOnlineSession* namedSession = sessionInterface->GetNamedSession(SESSION_NAME);” I find my session
• With the search results, there is no session
• In my second device, FNamedOnlineSession nor FindSession() are able to find my sessions

I believe I wrote up a lot of details, hopefully you’re able to help me, since I’m not able to spot the problem at all.
Thanks a lot for your help in advance

I noticed another thread with the same problem and I solved it in the same way.
In the sessionSearch I needed to add this:

sessionSearch->QuerySettings.Set(SEARCH_PRESENCE, true, EOnlineComparisonOp::Equals);
