JoinRandomRoom failed. Client is on GameServer (must be Master Server for matchmaking) and ready

I would really appreciate it if you guys could help. I think it has something to do with the callbacks but I am not sure what exactly.

  • Hi @ECTheHunter,

    Thank you for choosing Photon!

    Like the error message says: in order to call JoinRandomRoom you need to be connected to Master Server, which means you need to be outside of rooms.
    So it looks like you try to join a random room while still joined to one.
    What you need to do is leave the room you are currently joined to, wait until you're connected to Master Server using the proper callback and then you can try to join another random room.
  • thanks
  • It can happen if you double click and meanwhile you are already in the room.
  • So the room was created successfully? And you click the create button again to report an error?
  • I found a tutorial on the Internet, and when I was doing the UI for displaying the room list, I double-clicked the Create Room button to report this error, and the list did not produce a room prefab, but it can. I don’t know what to do. Any hints thanks
  • So the project progress is stuck
