Servertravel doesn't work, kicks everyone back to lobby map

Hi,

I followed the UE Blueprint Multiplayer Tutorial, and while I thought I followed everything, when I start the game it kicks everyone back to the main lobby map.

Am I doing something wrong? Is there something that could’ve been done wrong? Is there any way of doing it that doesn’t involve the servertravel console command? I’ve exhausted all my ideas for this :frowning:
