PUN OpGetRegions with correct AppID fails with Missing value 224 (GetRegionListRequest.ApplicationId

mwk888

We're using PUN+ 1.76, everything works fine for connecting to regional servers and playing MP games.

But when we try to get the region list by calling PhotonNetwork.networkingPeer.OpGetRegions() it always fails with this error:

Operation failed: OperationResponse 220: ReturnCode: -2 (Missing value 224 (GetRegionListRequest.ApplicationId)
). Parameters: {} Server: NameServer

Our steps:

• - PhotonNetwork.networkingPeer.ConnectToNameServer()
  
• - Wait for PhotonNetwork.connectionStateDetailed == ClientState.ConnectedToNameServer
  
• - log PhotonNetwork.PhotonServerSettings.AppID to confirm it is set and correct (it is)
  
• - PhotonNetwork.networkingPeer.OpGetRegions(PhotonNetwork.PhotonServerSettings.AppID)
  
• - PUN logs the error noted above
  

btw we get the same error if we call other higher level methods while connected to name server, e.g. PhotonNetwork.ConnectToBestCloudServer()

The code for OpGetRegions() is simple and I can see it sets the AppID param:
parameters[(byte)ParameterCode.ApplicationId] = appId;
so no idea what to try next. Is this a server bug? Something we are doing wrong which is giving a confusing error response?

Thanks for help!

I did a little script to reproduce this and could make it work.
Most likely, you didn't set the AppId (which is in the settings but not in the NetworkingPeer, unless you ConnectUsingSettings()).

Use this as reference:

using UnityEngine;
using System.Collections;
using Photon;

public class ConnectAndGetRegions : PunBehaviour {

	// Use this for initialization
	void Start ()
    {
        PhotonNetwork.networkingPeer.AppId = PhotonNetwork.PhotonServerSettings.AppID;
	    PhotonNetwork.networkingPeer.ConnectToNameServer();
	}

    public override void OnConnectedToPhoton()
    {
        PhotonNetwork.networkingPeer.GetRegions();
    }

    void Update()
    {
        if (PhotonNetwork.networkingPeer.AvailableRegions != null && PhotonNetwork.networkingPeer.AvailableRegions.Count > 0)
        {
            Debug.Log("PhotonNetwork.networkingPeer.AvailableRegions.Count: " + PhotonNetwork.networkingPeer.AvailableRegions.Count);
            this.enabled = false;
        }
    }
}

Thanks, yes I added this before I connected to name server:

PhotonNetwork.networkingPeer.AppId = PhotonNetwork.PhotonServerSettings.AppID;

and it works now

Hi,

I am using PUN 2 in latest version of UFE (Universal Fighting Engine). When I am playing online game, I am getting following error,

GetRegions failed. Can't provide regions list. ReturnCode: -2: Empty application id

Could you please help me to resolve this issue.

Tobias

Please read the error message fully. Then check your application id.
The docs will tell you how to set up your app.

Thank you for the reply. I am getting following full error message.

I have added App Id in Photon Server Settings, but still I am getting above error. I am using photon cloud in our project.
