Adding Google GCM Api Key Azure Notification Hub Error

Question

We are trying to add our GCM API key to the azure notification hub and we are receiving the following error:

SubCode=40000. Failed to validate credentials with GCM. Error is The remote server returned an error: (401) Unauthorized...TrackingId:410c0e33-0c38-1823-8a62-2519627c76a2_M1_G19,TimeStamp:9/19/2014 10:08:32 AM

We have setup our GCM API key to allow any IP address and we have also tried registering from code like below but with the same error:

  NamespaceManager mgr = NamespaceManager.CreateFromConnectionString(conn);
  var hub = mgr.GetNotificationHub("<hubname>");


  hub.GcmCredential = new GcmCredential("<apikey>");
  mgr.UpdateNotificationHub(hub);

Are we missing something quite obvious here?

Answer 1

SubCode=40000. Failed to validate credentials with GCM.

This will probably fix this error:
