Unity RPS demo not working with LoadBalancing Server

I'm setting a new Photon server for a new game and decided to start fresh new Photon server v4 and run the Unity demo with it to test and I got error when I was running the RockPaperScissors demo. The server didn't return userId after the client connected to server and when I tried to join the room via joinrandomroom this error pop up:

Operation failed: OperationResponse 226: ReturnCode: -2 (Join failed: UserId is not set, checkUserIdOnJoin=true expects a UserId.). Parameters: {} Server: GameServer

Is there any way to fix this. does LoadBalancing not build to run this demo? Note that I can run the demo with PhotonCloud easily.

Both PUN+ and PhotonServer are latest version.
