Исключение PushSharp: учетные данные, предоставленные пакету, не были распознаны

Я получаю приведенное ниже исключение для push-уведомлений IOS с помощью Pushsharp. Я просмотрел много статей, но не получил четкого представления о том, как действовать. Andoid работает нормально, только проблема с этой IOS.

Исключение:

System.ComponentModel.Win32Exception (0x80004005): The credentials supplied to the package were not recognized

МОЙ код:

    PushBroker push = new PushBroker();
    push.OnNotificationSent += NotificationSent;
    push.OnChannelException += ChannelException;
    push.OnServiceException += ServiceException;
    push.OnNotificationFailed += NotificationFailed;
    push.OnDeviceSubscriptionExpired += DeviceSubscriptionExpired;
    push.OnDeviceSubscriptionChanged += DeviceSubscriptionChanged;
    push.OnChannelCreated += ChannelCreated;
    push.OnChannelDestroyed += ChannelDestroyed;
    var appleCert = File.ReadAllBytes(@"C:\Data\abc\Cert\CCDevelopment.p12"); 
    push.RegisterAppleService(new ApplePushChannelSettings(false, appleCert, "password")); //Extension method
   push.QueueNotification(new AppleNotification()                                                                      .ForDeviceToken("tokenId") //dev
                                 .WithAlert(msg) //load
                                 .WithBadge(1));  //
