chat Manager -> Failed parsing address

Photon Pun as it's own works fine i can connect an all but not the chat.

I have already checked the app ID of the chat, that is okay.

public class PhotonChatManager : MonoBehaviour, IChatClientListener

{

   ChatClient chatClient;

   public int ID = 10;

   void Start()

   {

       Application.runInBackground = true;

       chatClient = new ChatClient(this);

       AuthenticationValues authValues = new AuthenticationValues(ID.ToString());

       chatClient.Connect(PhotonNetwork.PhotonServerSettings.AppSettings.AppIdChat, PhotonNetwork.AppVersion, authValues);

       Debug.Log(chatClient.CanChat);

   }

   public void Update()

   {

       chatClient.Service();

   }

   public void DebugReturn(DebugLevel level, string message)

   {

       Debug.LogWarning(message);

   }

}

thanks for all who want to help me with this.
