Can't Create A Steam Session

I can’t create a steam session, with the advanced session plugin or with the classic “create session” one.

When I create the session with a custom event, I opened my level with the console command using “?listen”, I’ve tested too with the “Open Level” blueprint node. Both didn’t worked.

When I check “LAN” on the two “create session” nodes, it works in a packaged build. But If I don’t (LAN unchecked) I does not work.

DefaultEngine.ini : [/Script/Engine.GameEngine]
!NetDriverDefinitions=ClearArray

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

Blueprints :

I personally don’t use the Advanced Sessions Plugin, Unreal has a Multiplayer Steam Tutorial on their youtube page, it may be for 4.11 or so but everything works in 4.19.

I explained that I used the normal session node for test purposes. Even with the help of their tutorial, that didn’t work, that didn’t fix my problem.
