Timeout exception

Hello.

Sometimes I have Timeout exception when I send APN to apple server. Below is my exception StackTrace:

System.AggregateException: One or more errors occurred. —> System.TimeoutException: The operation has timed out. at HttpTwo.Http2Client.<Send>d__19.MoveNext() — End of stack trace from previous location where exception was thrown — at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at HttpTwo.Http2Client.<Send>d__17.MoveNext() — End of stack trace from previous location where exception was thrown — at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at HttpTwo.Http2Client.<Post>d__15.MoveNext() — End of inner exception stack trace — at System.Threading.Tasks.Task`1.GetResultCore(Boolean waitCompletionNotification) at PushNotificationAPI.Controllers.AppleController.SendNotification(String jwtToken, String deviceToken, String topic, Object payload, Boolean isProduction) at PushNotificationAPI.Controllers.AppleController.PushNotification(String kid, String iss, String topic, String authKey, Boolean isProduction, String deviceToken, Object payload) —> (Inner Exception #0) System.TimeoutException: The operation has timed out. at HttpTwo.Http2Client.<Send>d__19.MoveNext() — End of stack trace from previous location where exception was thrown — at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at HttpTwo.Http2Client.<Send>d__17.MoveNext() — End of stack trace from previous location where exception was thrown — at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at HttpTwo.Http2Client.<Post>d__15.MoveNext()<—

My code here:

private AppleResponseModel SendNotification(string jwtToken, string deviceToken, string topic, object payload, bool isProduction)
        {
            var domain = isProduction ? "https://api.push.apple.com:443" : "https://api.development.push.apple.com:443";
            var uri = new Uri($"{domain}/3/device/{deviceToken}");

            var client = new Http2Client(uri);

            var headers = new NameValueCollection
            {
                {"apns-id", Guid.NewGuid().ToString()},
                {"apns-expiration", "0"},
                {"apns-priority", "10"},
                {"apns-topic", topic},
                {"authorization", $"bearer {jwtToken}"}
            };

            var body = Encoding.ASCII.GetBytes(JsonConvert.SerializeObject(payload));

            var response = client.Post(uri, headers, body).Result;

            var responseBody = Encoding.ASCII.GetString(response.Body);
            var notificationId = response.Headers["apns-id"];

            return new AppleResponseModel(response.Status, responseBody, notificationId);
        }

Could you please help me what going wrong?

@Jent05 Unfortunately, I doubt that HttpTwo library supports that. When I use it, I use lock to make sure other thread finished using HttpTwo.

This happened because it is talking to wrong TCP connection somethings. I have some fixes in my fork.
