Can't create Steam Sessions (Steam Sockets)

Honorenji · July 4, 2021, 12:30am

Hello,

I am creating a Multiplayer game which uses Steam.
Now I already have a AppID and the game is available on Steam, but for some reason I am having issues when creating a session.

This is the relevant part which gives the error when I cmd run a Standalone Game with -game -log:

[2021.07.02-11.05.54:525][530]LogModuleManager: Warning: ModuleManager: Unable to load module 'SocketsSTEAM'  - 0 instances of that module name found.

It says there is no module to load called SocketsSTEAM.

This is in my DefaultEngine.ini file:

I have enabled the Steam plugins in the editor as well.

It’s a shame the documentation is so poor.
Please if anyone can help me out, or if you need more files, let me know!
Many thanks!

Same here, but don’t hold your breath on getting any kind of help with it.

your server’s ports must be between 27015 and 27050 to start listening with SteamNetDriver. If the ports are exactly 27015 or 27050 it won’t work, it needs to be between that range, if it’s out of range the server will also work, but it won’t show up in the steam server list. Start your server like “-log -port 27022” This link will help you: Ports Required for Steam . Do not forget to open the ports on the modem and windows, you also need to disable the firewall.

I’m using SteamSocket plugin.

Thanks for your post! I don’t know if it helped the person initially asking but I just found it and it seems the changes I borrowed from your config file was able to make SteamSockets work for me in Lyra.

I haven’t done any extensive testing with it yet but thanks again!

Suundumused · January 1, 2023, 9:43pm

What changes did you do?

T7g · January 2, 2023, 3:39am

If I were to guess what actually fixed my issue (I did add a few changes from your example but this one was the most significant I think.)

+NetDriverDefinitions=(DefName=“GameNetDriver”,DriverClassName=“/Script/SteamSockets.SteamSocketsNetDriver”,DriverClassNameFallback=“/Script/SteamSockets.SteamNetSocketsNetDriver”)

as opposed to…

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

I did get it working and was able to create/join games with my Lyra example through Steam. I’d like to note though that there seems to be a bug with 5.1 that causes the server to refuse packets from the client sometimes. I can’t reproduce it all the time but you’ll see it in the console output on the server side if it can’t verify the packets.

One last note, “bUseLobbiesIfAvailable = false” I noted could also have something to do with me being able to get joining games working properly- but that stuff comes after Steam Sockets are fixed and the server can create a game properly.

Did you use Shipping build when connecting successfully? Did you disable net.VerifyNetSessionID and VerifyNetClientID? I was able to connect in Development build but not in Shipping.

T7g · January 3, 2023, 4:39am

I haven’t tried cooking a shipping build yet but I am aware that there was a bug that has since been fixed in those console commands. I am not sure if my github source is from before or after that- but I know what the error message looks like and I’m a ways away from shipping what I’m working on.

Anoberia · January 3, 2023, 5:29am

I had to make false those flags as well as fixing the code which was wrong cvar. (here) Now I can connect in Shipping build successfully. I hope it won’t broke someway I will make dedicated server support for this game and it looks like it’ll be much more difficult since I spent 3 months just for connecting P2P. But it helps me to learn a lot about Sockets, Debugging, Source Version etc.

The NetDriverDefinitions change that you mentioned did make it so that I could create P2P sessions properly and they show up in the “Browse” list as expected, but when I try to join them I get a net driver error like this.

At the moment my INI file looks like this.

bUseLobbiesIfAvailable = false
bInitServerOnClient=false

[/Script/OnlineSubsystemSteam.SteamNetDriver]

I’m pretty stumped as to how to resolve this so any help is greatly appreciated!
