“operation set (252) not called because client is not connected” And I have one more problem.

Hello, I just started using PUN 2 and recently I made a pause menu to my multiplayer game and in the pause menu there is a Disconnect button.

Code (CSharp):

1.  
2. public void Disconnect()
3. {
4. PhotonNetwork.LeaveRoom();
5. SceneManager.LoadScene(0);
6. }

And when I press the button i get this error “ operation set (252) not called because client is not connected or not ready yet. client state leaving”. I am wondering does that mean that my player is not fully connected, because I am having another problem which is that sometimes only one of the players sees the player, does it have something to do with the error and how can I fix both issues? Thanks in advance!

 

We found an issue with SetProperties recently and fixed it in PUN 2.18.1. Maybe you update and give it another go.
If this is v2.18.1, we'd need to know more about the timing of this use case.
After leaving a room, we need to apply properties locally but not send them. This check apparently isn't working in your case.

 

Hello, thanks for the reply! I am using PUN 2.18.1 and sometimes when I press disconnect and I get the error but then it does not go back to the menu scene.

 

Do you know how to fix the error? If so, how?

 

You should stop calling the operation (with code 252) once you disconnect. Apparently your code continues to call it.
Along with the error code, you get a callstack. Check which code called the operation and make sure it only runs while connected.

 

@tobiass I have been having this problem. So far I have checked. It seems the PhotonMono is still not destroyed.
Scenario:
After the multiplayer match is done. Result screen is showed, then clicking back to go to main menu is causing this issue. before calling main menu scene. I called leave room & Disconnect. But, when it reaches mainmenu. PhotonMono GO is not destroyed and its calling PhotonNetwork.NewSceneLoaded(); at Start().

Why PhotonMono is not destroyed. Am I doing something wrong?

Code (CSharp):

1. public void OnLoadMainMenu ()
2.     {
3.           PhotonNetwork.LeaveRoom();
4.           PhotonNetwork.Disconnect();
5.           SceneManager.LoadScene(1);
6.     }

After looked into some other forums. I have tried this code:

Code (CSharp):

1. private IEnumerator WaitForDisconnect ()
2.     {
3.         PhotonNetwork.LeaveRoom();
4.         PhotonNetwork.Disconnect();
5.         while (PhotonNetwork.IsConnected)
6.             yield return 0;
7.         SceneManager.LoadScene(1);
8.     }

But, that stays in the multiplayer scene and never leaves.

Help me out!

Thanks!

 

PhotonMono is PUN's integration with Unity engine events. Some are only available to MonoBehaviours, so PhotonMono is created at runtime and marked with DontDestoryOnLoad. It has to stay there, even when you disconnect.

 

@tobiass Ya, But, when it loads back to main menu from Multiplayer scene (Where I called Leave Room & Disconnect).
Photon Network call is initiating from the start of that function.

So, that's what causing me the issue Operation set (252)

 

A callstack might help.

 

@Seven007 What's happening is that you're leaving the scene too quickly.

Use this.

Code (CSharp):

1. public void LeaveRoom()
2. {
3.     PhotonNetwork.LeaveRoom();
4. }
5.  
6. public override void OnLeftRoom()
7. {
8.     SceneManager.LoadScene(0);
9.  
10.     base.OnLeftRoom();
11. }

Also make sure you are using MonoBehaviourPunCallbacks

 

I'm getting the same issue. It seems to only happen when I'm trying to rejoin a room.

As you can see in my logs, isConnectedAndReady is TRUE before I attempt to call RejoinRoom. And despite getting the error, it still successfully joins the room afterward.



I'm using PUN 2.18.1 on 2019.3.12f1

 

Hii. Did you solve your issue guys? I am facing the same.

 

yes i solved it by following this

 

Ok. Solved, Thanks.

 

That really worked. Thanks man

 

Hi,

i am having exactly the same situation ( game pause menu, was trying to load menu too quickly ).

However when i call this:

Code (CSharp):

1. if (PhotonNetwork.InRoom)
2.     PhotonNetwork.LeaveRoom();

the LeftRoomCallback doesn't get called

Code (CSharp):

1.  
2. // Dasn't get called because player gets deleted
3. public override void OnLeftRoom()
4. {
5.     PhotonNetwork.LoadLevel("Menu");
6. }

because the player gets deleted and i get this log message:
Network destroy Instantiated GO: Car_01(Clone)1001

Is it normal that the player gets deleted in this case, because i thought it has to be deleted manually ?

 

By default, networked game objects are cleaned up (destroyed) when the creator leaves.

You can disable the clean up entirely. Set RoomOptions.CleanupCacheOnLeave = true when you create a room.

It's also possible for the Master Client to instantiate "Room Objects", which stay in the room, you can load networked objects with the scene.

 

public void OnClick_RestartGame()
{
PhotonNetwork.LeaveRoom();
}

public override void OnLeftRoom()
{
SceneManager.LoadScene("Lobby");

base.OnLeftRoom();
}

I have my restart game attached to a button, with the above code. Yet, I can't seem to get this to work. What am I doing wrong? I just want to load from game scene back to lobby scene.

 

Is this PUN 2? The script which implements OnLeftRoom seems to extend MonoBehaviourPunCallbacks? Make sure this script's OnEnable() / OnDisable() call base (so they get registered for the callback).

Enable the SupportLogger in the settings and check if that also doesn't log OnLeftRoom().

 

Hi I have the same issue but a bit forward so I called (PhotonNetwork.LeaveRoom() and then the game freeze and its not disconnecting, there is no error and the player have being destroy like it should be but its just stop.
look:

 

Someone can help maybe?

 

There is no known reason why this should happen due to PUN. Can you reproduce this with any of the samples we provide with the package?
Is there a newer version of PUN which you could update to? And which version of Unity is this?

 

2020.2.4

 

i am using pun 2 so i think its the newer version no?

 

there is something that may cause this issue?

 

I think the issue is somehow caused within your project, not by PUN itself. So please try to reproduce with one of our demos. If you can, we can have a look.

PUN 2 also has a version number. Look at PhotonNetwork.PunVersion.

 

I will tell you what, this is happening only in the game scene in the menu i have also leave Room button that program the same and he works

 

So i have no idea why this is happening
.

 

hi, I have this issue. I call changing scene in OnLeftRoom Method and it's working without error. so o think you cant call changing scene before the LeaveRoom method sends the callback.



public void LeaveRoom()
{
PhotonNetwork.LeaveRoom();
}



public override void OnLeftRoom()
{
SceneManager.LoadScene("Menu-Scene");
}

 

what is your issue? habibizeinab9

 

In my case, I was getting this error when I was re-joining a room with a different "nickname"(or possible other player properties). Keeping the same nickname when rejoining rooms has solved the problem.

 

i have a problem with exit to menu from game scene
https://stackoverflow.com/questions...he-game-scene-into-the-menu-scene-hits-an-err

 

I've been having the same problem and found the FIX
So basically the problem is you're calling scenemanager.loadscene before photon manages to disconnect from the room, what you should do instead is just call PhotonNetwork.LeaveRoom()
The inside of the "public override void OnLeftRoom()" you should add the scene changin code

also to be able to use that callback you'll need your class to inherit from MonoBehaviourPunCallbacks

EXAMPLE

I was getting this error on

Code (CSharp):

1.     public void leaveServer()
2.     {
3.  
4.         SceneManager.LoadScene("MainMenu");
5.  
6.         PhotonNetwork.LeaveRoom();
7.     }

So I just replaced it with

Code (CSharp):

1.     public void leaveServer()
2.     {
3.  
4.         PhotonNetwork.LeaveRoom();
5.  
6.     }
7.     public override void OnLeftRoom()
8.     {
9.         SceneManager.LoadScene("MainMenu");
10.     }

 

Hello, thank you for the recommendation, this has helped, but in my case I have encountered a new problem.
When I connect to the lobby this error occurs:
Operation JoinLobby (229) not called because client is not connected or not ready yet, client state: JoiningLobby

Based on this forum post, I found out that this is caused by me running the JoinLobby() function twice:
https://forum.photonengine.com/discussion/17696/problem-joinlobby

I call it in the OnConnectedToMaster() method and then in the Start() method,
Without it being called in OnConnectedToMaster, it all falls apart.
Without it being called in Start, players after a fresh connection can't see the rooms listed. They have to create their own room and leave it (so then the OnConnectedToMaster() is called and they are connected to the lobby), so the OnConnectedToMaster method is not called after fresh connection... which strikes me as odd.

I somehow tried to check if I'm connecting to Lobby but it did not help (I guess PhotonNetwork.InLobby returns false while joiningLobby)
I tried this:

Code (CSharp):

1.  private void Start()
2.     {
3.         StartCoroutine(waitToConnect());
4.     }
5.  
6.     IEnumerator waitToConnect() {
7.         while(!PhotonNetwork.IsConnectedAndReady)
8.             yield return null;
9.         roomInputField.characterLimit = 13;
10.         if (!PhotonNetwork.InLobby) PhotonNetwork.JoinLobby();
11.     }

Error persisited, so I brute-forced it like this:

Code (CSharp):

1. private void Start()
2.     {
3.         StartCoroutine(waitToConnect());
4.     }
5.  
6.     IEnumerator waitToConnect() {
7.         while(!PhotonNetwork.IsConnectedAndReady)
8.             yield return null;
9.         roomInputField.characterLimit = 13;
10.         StartCoroutine(waitASec());
11.     }
12.  
13.     IEnumerator waitASec() {
14.         yield return new WaitForSeconds(1f);
15.         if (!PhotonNetwork.InLobby) PhotonNetwork.JoinLobby();
16.     }

This helped with the error, but with this solution, after rejoining the lobby scene, after the match ended. The players can't see new rooms (so I would guess they are not connected to the lobby), but this time creating a new room and leaving it won't help.

I would be grateful for any insights and comments!

 

Refactor your code to rely on the PUN callbacks. IsConnectedAndReady is not covering all the cases you want to be aware of. You can inherit from MonoBehaviourPunCallbacks and override the individual methods (they are empty in the base). So you know when you arrived on the Master Server, joined a lobby, etc.

 

How to fix this issue,i'm using PUN2?
"Operation ChangeGroups (248) not allowed on current server (MasterServer)"

 

Do not call this on the Master Server. Only in a room.
