New multiplayer setting broke Network Lobby

Hi all, For my final year project i'm using the network lobby asset for multiplayer, which was working fine. on opening the project, i noticed in the services tab, the multiplayer option was different, it no longer has an on off switch, but you are able to configure it. The problem is now my client cannot join an online game. it just gets stuck on connecting. Does anyone know a fix for this. Thanks, Chris.
