Describe your issue:

Sending push notifications success BUT not receiving any

static void Main(string[] args)
{

        try
        {
            var config = new ApnsConfiguration(ApnsConfiguration.ApnsServerEnvironment.Production,
             Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "SSLCertificates.p12"), "1A@$f234", false);
            
            var apnsBroker = new ApnsServiceBroker(config);
            apnsBroker.ChangeScale(10);
            
            apnsBroker.OnNotificationFailed += (notification, aggregateEx) => {

                aggregateEx.Handle(ex => {

                    if (ex is ApnsNotificationException)
                    {
                        var notificationException = (ApnsNotificationException)ex;

                        var statusCode = notificationException.ErrorStatusCode;
                        Console.WriteLine("Apple Notification Failed: ID= " + apnsNotification.Identifier + " Code= " + statusCode);
                        Console.WriteLine(ex.Message);
                        if (ex.InnerException != null)
                            Console.WriteLine(ex.InnerException.Message);
                    }
                    else
                    {
                        Console.WriteLine("Apple Notification Failed for some unknown reason : " + ex.InnerException);
                    }

                    return true;
                });

                Console.WriteLine("Apple Notification Sent!");
            };

            apnsBroker.Start();

            foreach (var deviceToken in MY_DEVICE_TOKENS)
            {

                    Payload = JObject.Parse("{\"aps\":{\"alert\":{\"title\":\"Test\",\"body\":\"Test push\"},\"url-args\":[]}}")
                });
            }

            apnsBroker.Stop();

        }

i uploading my certification on onesignal site for test and it's work but this code is run and get success sent message but not showing any notification on safari

[isfo]

any news?

[snoopydo]

You mention Safari, browser push requires an encrypted & signed payload which your example doesn't do.
Double check that the provisioning profile that your iOS app is using the same certificate as the service that sends the notifications.

[zibrohimov]

Same issue. I see how many people are facing this problem and it is unbelievable there is still no good response.

The case is, it is hitting the success event, but the device is not receiving any notification on iOS.

Trying http://pushtry.com/ with same certificate, password, and device token receives notification without any problem.

This problem should have a valid explanation, as MANY-MANY people are facing the same.

I would now look at the payload your sending. Apple accepting it doesn't mean its able to be processed by your app, either the library or your app could be quietly eating the notification because it can't parse the payload.
I see from the example that you're using an object for the alert property, try just passing simple text message (which I imagine pushtry will be doing) via this property, also remove the empty url-args property. Also the expiration datetime is set using local time, I would assume this should be UtcNow.

I had this problem and in my case, my payload was missing aps: {}

I was sending

{
  "alert": "test",
  "badge": 1,
  "sound": "default",
  "category": "none"
}

instead of

{
  "aps": {
    "alert": "test",
    "badge": 1,
    "sound": "default",
    "category": "none"
  }
}

Thats what fixed it for me

[yogeshkv777]

same issue here... getting success for both GCM and APNS but notifications are not being sent... no idea where is the problem.

[yogeshkv777]

any update on this issue? same here... getting success response but notification not delivered to device, creating very uncertainty.

Hello,

You should use this server side library for push notification in c#:
https://github.com/bytefish/FcmSharp
The steps described to use it, includes a need to reference the serviceAccountKey.json file that is downloaded from the firebase console. This is the file that enables authentication on the channel. Without this enabling the notification sending is not reliable.
