Photon closes the room after connecting the players without reason. ReturnCode: 32764 (Game closed).

When I tested my application with a small number of players (1-5 players), everything works impeccably. But as soon as the players continue to room (5-10 players) the photon close room and the players cannot connect. Photon disconnects with the error: ReturnCode: 32764 (Game closed).

My room options:

var options = new RoomOptions();

options.MaxPlayers = 32;

options.PublishUserId = true;

options.IsOpen = true;

options.IsVisible = true;

options.PlayerTtl = 1;

options.EmptyRoomTtl = 1;

bool room = PhotonNetwork.JoinOrCreateRoom("MY_ROOM_NAME", options, null);

I have a dedicated photon server with a free license for 100 CCU;

Application on Unity - WebGL

What could be the reason for this error? What am I doing wrong?
