Sessions not found over internet - Only locally [STEAM]

Hello again,

I have recently built my session browser following the helpful video posted on the UE YouTube channel a while back.

I am however having some issues and I’m not sure where to begin tackling it.
I have set it up so that it works like a traditional server browser, with refresh, host and direct connect buttons. When I click to host the game on my machine, the session creates and I’m loaded into the level. However the issue I’m having is that my friends cannot find the session via the browser online, however I can find it locally.

I have been through the basics over and over such as making sure the session create/find is not set to LAN.
I have updated the steam .dll’s to the latest and have double checked it is all correct for the steam setup.
I have also forwarded the needed ports so that isn’t blocking me either.

I am happy that Steam is set up correctly as the overlay appears and the game can fetch the users Steam username. However the game is currently setup to use the default app id 480 and I was wondering if this would cause an issue for the sessions not being found over the net?

Just so I can show the DefaultEngine file is setup correctly:

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

[OnlineSubsystem]
DefaultPlatformService=Steam
PollingIntervalInMs=20

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480
GameServerQueryPort=27015
bRelaunchInSteam=false
GameVersion=1.0.0.0
bVACEnabled=1
bAllowP2PPacketRelay=true
P2PConnectionTimeout=90

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

Any help to get my sessions showing online would be great :slight_smile:

Cheers,

Feel this may have gotten lost overnight so I’m going to bump it.

So this seems to be an intermittent thing… So I am assuming it’s a draw-back to using the 480 App ID. Any one able to confirm that for me? Also, as the game is running via steam, is it best practice to change the port from 7777-7778 to Steams 27015?

i have the exact same problem. no idea how to fix it…

if you find a solution, please send tell me.

thank you

Well I’ve got Steam working over the internet, tested with someone 50KM away, but within the same country. I’ve read something about issues with different countries/continents when using the 480 App ID.

Here’s what I’ve got on some of the settings.
DefaultEngine.ini
[OnlineSubsystem]
DefaultPlatformService=Steam
PollingIntervalInMs=20

[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480
GameServerQueryPort=27015
bRelaunchInSteam=false
GameVersion=1.0.0.0
bVACEnabled=1
bAllowP2PPacketRelay=true
P2PConnectionTimeout=90
 
[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="/Script/OnlineSubsystemSteam.SteamNetConnection"

projectname.Build.cs

PublicDependencyModuleNames.AddRange(new string[] { 
 	        "OnlineSubsystem",
 	        "OnlineSubsystemUtils"
         });

        DynamicallyLoadedModuleNames.Add("OnlineSubsystemSteam");

		//Uncomment if you are using Slate UI
		//PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });
		
		//Uncomment if you are using online features
		PrivateDependencyModuleNames.Add("OnlineSubsystem");
		if ((Target.Platform == UnrealTargetPlatform.Win32) || (Target.Platform == UnrealTargetPlatform.Win64))
		{
			if (UEBuildConfiguration.bCompileSteamOSS == true)
			{
				DynamicallyLoadedModuleNames.Add("OnlineSubsystemSteam");
			}
		}

projectname.Target.cs

public projectnameTarget(TargetInfo Target)
	{
		Type = TargetType.Game;
        bUsesSteam = true;
	}

I hope that this might help you to find what’s wrong.

I did. here is how:

on the [/Script/Engine.Engine] part

the last line add:

+NetDriverDefinitions=(DefName=“GameNetDriver”,DriverClassName=“OnlineSubsystemSteam.SteamNetDriver”,DriverClassNameFallback=“OnlineSubsystemUtils.IpNetDriver”)

also I did removed all the +NetDriverDefinitions and -NetDriverDefinitions
