Push-уведомления с формами Xamarin: MobileServiceClient RegisterAsync завершается с ошибкой 401 в Xamarin.Android

Я следую учебному пособию https://docs.microsoft.com/en-gb/azure/app-service-mobile/app-service-mobile-xamarin-forms-get-started-push, (добавление push-уведомлений в проект Android)

Вот метод, который связывается с сервером: 

async Task SendRegistrationToServerAsync(string token)
    {
        try
        {
            // Formats: https://firebase.google.com/docs/cloud-messaging/concept-options
            // The "notification" format will automatically displayed in the notification center if the 
            // app is not in the foreground.
            const string templateBodyFCM =
                "{" +
                    "\"notification\" : {" +
                    "\"body\" : \"$(messageParam)\"," +
                      "\"title\" : \"Xamarin University\"," +
                    "\"icon\" : \"myicon\" }" +
                "}";

            var templates = new JObject();
            templates["genericMessage"] = new JObject
            {
                {"body", templateBodyFCM}
            };

            var client = new MobileServiceClient(Organizer.App.MobileServiceUrl);
            var push = client.GetPush();

            await push.RegisterAsync(token, templates); // CRASH!!!

            // Push object contains installation ID afterwards.
            Console.WriteLine(push.InstallationId.ToString());
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
            Debugger.Break();
        }
    }

Сбой при выполнении метода RegisterAsync:

Ответ от сервера:

{StatusCode: 401, ReasonPhrase: «Unauthorized», версия: 1.1, содержимое: System.Net.Http.StreamContent, заголовки: { Передача-кодировка: чанки Сервер: Microsoft-HTTPAPI / 2.0 Дата: пт, 31 августа 2018 13:21:44 GMT Content-Type: application / xml; кодировка = UTF-8 }}

Что необходимо настроить на сервере, чтобы мы не получили ошибку 401?

Или что еще может быть не так?

Вот полная MainActivity: 

public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
    private const string TAG = "ANDROID_PUSH_NOTIFICATION";
    protected override void OnCreate(Bundle bundle)
    {

        System.Diagnostics.Debug.WriteLine("In OnCreate");
        TabLayoutResource = Resource.Layout.Tabbar;
        ToolbarResource = Resource.Layout.Toolbar;

        base.OnCreate(bundle);

        global::Xamarin.Forms.Forms.Init(this, bundle);
        LoadApplication(new App());

        if (Intent.Extras != null)
        {
            foreach (var key in Intent.Extras.KeySet())
            {
                var value = Intent.Extras.GetString(key);
                Log.Debug(TAG, "Key: {0} Value: {1}", key, value);
