Pushsharp: IOS通知在本地工作，但不在实时服务器上

Pushsharp IOS通知在本地工作，但不在实时服务器上，我甚至无法跟踪错误在哪里，它不会触发任何以下事件，谁能建议任何提示调试。我需要在服务器上做一些设置吗?下面是我的代码。

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;
    push.RegisterAppleService(new ApplePushChannelSettings(appleCert, "xxx"));
push.QueueNotification(new AppleNotification()
                     .ForDeviceToken("toked ID here") //dev
                     .WithAlert(msg)
                     .WithBadge(7)
                     .WithSound("sound.caf"));
