How can I connect players to the game server?

Hi, I'm new to Playfab and to multiplayer in general. I'm working on an online mobile game that must have a lot of users online in the same server. I've followed different tutorials and I've managed to create a custom server and a matchmaking queue. The problem is that when I try to use RequestMultiplayerServerRequest API I get stucked in waiting for server response. If I try to skip the matchmaking and connect directly to the server I get this error :

MultiplayerServerNotFound - DeploymentNotFoundForRegion - Deployment(s) {xxxxxx} was not found in any of the regions specified - {NorthEurope}

I've checked my Game Manager and I've specified the server region.

Can someone tell me what I'm doing wrong? My ID is 1B3AF
