Dedicated server player not authorized

I making simple booting the server using new multiplayer sdk. At start Initialize API, second im used method StartMultiplaySessionManagerAsync with all filled options. But when lobby handler trying create lobby i have error in server logs:

“SessionException: Player is not authorized”

I trying sign in server anonymously but it didn’t work display the same. It’s issue up by my site or it’s a bug ?

Since you are on the server and in a trusted boundary you might consider using the token that is available within the server context:

I believe that should allow you to access Lobby api’s and most other Unity Gaming services.
