PushSharp hangs after apnsBroker.QueueNotification()

[Poornima-singh]

What version of PushSharp are you using?

4.0.10

Describe your issue:

After apnsBroker.QueueNotification() the http request hangs. No response is received. I tried in Postman and also waited couple of hours but seems like the there is no response from APNs even failure is not received. Please can you help me solve this issue? Is this PushSharp service issue? certificate issue? or APNs issue?

What are the steps required to reproduce this issue?

Please provide any Exception Stack Traces

This is what I see in my debug console

Hello,
I have been debugging so the requests goes into hang state after
apnsBroker.Stop(); this command.

@Poornima-singh We were also facing this issue in PushSharp,
Assuming its because of - https://developer.apple.com/news/?id=c88acm2b
so we discontinued and implemented dotAPNS which support HTTP/2 APNs API ..
https://github.com/alexalok/dotAPNS
Hope this will help

@21pg Thank you so much for your response. I also implemented dotAPNS, but unfortunately, it works in local and gives error when published. My solution is an asp.net solution and is published in Azure as App Service. I get below error.
Failed to send a push. HTTP request failed: System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.\r\n ---> System.ComponentModel.Win32Exception (0x8009030D): The credentials supplied to the package were not recognized

I don't know if it's the right solution to share this issue, but are you aware of anything in this regard?
