JoinRoom failed. Client is on MasterServer but not ready for operations

Hi, I am really new at this. Would really appreciate if anyone could help. I am getting this error message when a client joins a room. So what I can understand is that the client is not IsConnectedAndReady. How can I make sure it is connected and ready so I can avoid this error??
I am able to connect after this error message though. Thanks.

Hi @Mozzz,

Thank you for choosing Photon!

What PUN version do you use?
What is the exact error message?

As it already hints/suggests, you probably need to wait for the OnConnectedToMaster callback to be able to call JoinRoom.

Hi @JohnTube,

Thank you for your response.

I am using Photon version 2.7.

The complete error message is as follows:

JoinRoom failed. Client is on MasterServer (must be Master Server for matchmaking)but not ready for operations (State: Joining). Wait for callback: OnJoinedLobby or OnConnectedToMaster.
UnityEngine.Debug:LogError(Object)
Photon.Pun.PhotonNetwork:JoinRoom(String, String[]) (at Assets/Photon/PhotonUnityNetworking/Code/PhotonNetwork.cs:1742)
Launcher:joinRoom(String, Action1) (at Assets/Scripts/Launcher.cs:235) Launcher:JoinRoom(String, Action1) (at Assets/Scripts/Launcher.cs:214)
RoomChoiceByNumberAction:b__0_0(String) (at Assets/PlayMaker/Actions/UIPanelManager/RoomChoiceByNumberAction.cs:15)
RoomChoiceByNumberPanel:JoinRoom() (at Assets/Scripts/UIPanels/RoomChoiceByNumberPanel.cs:105)
UnityEngine.EventSystems.EventSystem:Update()

I dont really understand that I need to wait for OnConnectedToMaster callback? OnConnectedToMaster has already been called in my case. I am trying to join the room now by pressing the join room button.

And also, how am I able to join the room after getting this error?

Hi @Mozzz,

So the client state is "Joining" which means the client is already in the process of joining a room.
So most likely you are hitting the Join button more than once.*
Try to add a flag or UI dialog or disable button while the client is trying to join the first time.

Hi @JohnTube ,

Thank you for your help, I managed to fix it. You were right in some way and set me on the right track. I was actually calling the join room function twice somehow. Thanks.
