Steam Friends requires AdvancedSessionGameInstance but I am using a standard GameInstance. Help!

You don´t need another Instance.

First:
If you are using the default premade GameInstance, create a new one from scratch. Simply righclick your Content Folder, Create basic Asset -> Blueprint Class. Open the Collapsed Box for “All Classes” and type Gameinstance into the searchfield. Select it!
This Gameinstance ist 1:1 the default gameinstance of the Engine. But, you can manipulate it

Now, open your custom Gameinstance.
Click on Class Settings. in the Top Header.
You now see the Class Options (per default) on the right side.
Look for the “Parent Class” Option. Change it to the AdvancedSessionGameInstance, instead of the simple GameInstance.
Look for the “Implemented Interfaces”. Hit “Add” and add the AdvancedSession Interfaces here.

Last:
Go into your Project Settings. Head to “Maps & Modes”. At the Bottom, you can select a Gameinstance. Select your custom one here.

That´s all.

I modified my game instance but I am having this error in the attachment. Since I swaped the Create Session with the Create Advanced Session the game works fine in Standalone but when I build and want to play I get disconnected from my lobby that used to work. So the multiplayer works in standalone but not when built. And so far I have changed only this one node. Also, the server hosts for a second then the session abruptly ends. Any ideas?
