Blueprint Session Problem

I tryed to make a multiplayer with sessions.
Create Session and Host Game works well but the Client not.
The Client serches for Sessions and add them to a List, now he can join those Sessions.
Once a Client joins the Session the Client cant controll the Pawn or look with the Camera, but the Pawn is spawned.

The Host can controll and walk without anny problems.

Any Idea ?

Thanks DarkSoe


No one have a idea ?
