Hello there.
I have a problem with steam online subsystem. I use UE5.3.2, downloaded advanced session and steam advanced session plugins, turn off other sessions plugins (e. g. EOS), added this code to DefaultEngine.ini:
[/Script/Engine.GameEngine]
!NetDriverDefinitions=ClearArray
+NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="/Script/SteamSockets.SteamSocketsNetDriver",DriverClassNameFallback="/Script/SteamSockets.SteamNetSocketsNetDriver")
[OnlineSubsystem]
DefaultPlatformService=Steam
[OnlineSubsystemSteam]
bEnabled=true
SteamDevAppId=480
[/Script/OnlineSubsystemSteam.SteamNetDriver]
NetConnectionClassName="OnlineSubsystemSteam.SteamNetConnection"
Then I packaged game with “Shipping” setting, added to packaged game “steam_appid.txt” file and write “480” in it. Steam menu opens correctly, sessions creates, can be found, but when I try to join my friend’s session (we have different accounts in one country), it said that it joins, but session level does not open at all. Like when creating session, it opens level with option “listen”, then it is found with “find advanced session” node, but when trying to join, it joins without opening needed level. What can be a problem?
