i try "get session state" "is player in session" "get session settings"
it work on steam but not work on lan (Online Subsystem Null)

Hello,
I played around with the plugin and followed a few different tutorials to build the engine from source and get a session up and running.
https://wiki.unrealengine.com/Dedica...er_Guide_Steam

Current state is:

• I am able to package the project with a dedicated server.exe,
• I can start it either with steam running or with all the different steam api dlls in the folder, without any errors (looks like it tries to find the api dlls and falls back on a running steam instance if it can't find them),
• I can NOT find it locally if I have steam running or the dlls beside the server.exe, even if searching for local matches,
• I can find a match if steam isn't running (doesn't matter if searching lan or online, it always finds it),
• I can find it Locally over steam > view > server, with steam running,
• but I can't find it in the Internet tab despite adding port forwarding in the modem and adding firewall exceptions for 7777 (Unreal) and 27015 (Steam Master Server).

Questions:

• Why does it not matter if searching LAN OR Internet with steam disabled?
• Why can't I find my server with Steam enabled on the Internet tab? (I know that the port forwarding should work because I hosted a Minecraft Server and that worked fine)

Okay, what are you trying to do, keep in mind that many of the newer versions of the engine have incorporated fixes that used to require this plugin. Think about an alternative solution to this plugin.

I want to host a dedicated server which should be visibel in the Internet tab of Steam.
What did they add in the newer versions? The basic create and find session nodes in BP (UE 4.20) only show Use Lan, how many Public Connections are allowed and how many results should be shown. Looks like I still require the plugin.
What would be the alternative?

Starting with 4.20 I'm seeing this error when packaging, anyone has a clue?

ERROR: System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Program Files\Epic Games\UE_4.20\Engine\Plugins\AdvancedSessions\AdvancedSessions\Intermediate\Build\Win64\UE4\Shipping\AdvancedSessions\AdvancedSessions.precompiled

You need to put the plugin in the project directory unless I start compiling the pre-compiled binaries out of IDE, 4.20 added a new file that is only generated with rocket builds.

Thank you, that worked!

Except that now I'm having the following:

LogOnline: Display: STEAM: Loading Steam SDK 1.39
LogOnline: Warning: STEAM: Steam API disabled!
LogOnline: Display: STEAM: OnlineSubsystemSteam::Shutdown()
LogOnline: OSS: Unable to create OnlineSubsystem module Steam
LogOnline: Verbose: OSS: Created thread (ID:11436).

Any ideas? This used to work on 4.19.

That isn't really true....I wish it was.

The authentication addition that they added in 4.20 for dedicated servers isn't relevant, I never provided a solution for that.

Really I do not understand. I freshly reinstall 4.20.2, run in standalone, I can see Steam. I package it, and I get:

UATHelper: Packaging (Windows (64-bit)):   LogStreaming: Display: Took  0.088s to configure plugins.
UATHelper: Packaging (Windows (64-bit)):   LogOnline: Display: STEAM: Loading Steam SDK 1.39

UATHelper: Packaging (Windows (64-bit)):   LogOnline: Display: STEAM: OnlineSubsystemSteam::Shutdown()
PackagingResults: Warning: STEAM: Steam API disabled!

From then on, I can't access Steam anymore unless I reinstall 7GB of stuff. I did not experience this with 4.19, and the only difference is the fact that I put the AdvancedSessions plugin into the project's directory (see above why).

Anyone has seen this?

Moving the plugin has no effect on the OnlineSubsystemSteam, are you packaging to Shipping? Because from shipping you need to include the App_ID.txt file or the steam subsystem will fail out. In development packaging it will run without that file.

You're certainly right. I added this detail because this is the only difference, and I thought that maybe it had an effect because now my project started having the Build.cs file. Documentation is inconsistent about whether we should include the Steam module in it or not (docs say yes, comments in the file say no). Also, yes, I do have the steam_appid.txt file in the shipping version.

Anyway thanks for confirming that this has nothing to do with the plugin per se, and you for sharing your work Morden Tral!

No, its because it not implemented in the Steam Subsystem, I expose it because Epic has it in their interface so it can be used even if it isn't currently implemented (third party subsystems for example can implement it, currently there aren't any built in ones that do).
