Hi,
I am currently using the token based protocol to send iOS push notifications to users via my application. However, there are several instances when I receive no response from the APN server and as a result the notification is not sent. For the configuration that I am relying on, I am still able to send notifications to other devices. Kindly provide assistance on how to resolve this.
If you are intermittently not getting any responses from APNs, this is likely a network issue in between. You would want to start by finding what the failure is. Have you checked your networking or TCP logs?
While it is possible to check why a specific push request may have failed at APNs side, if there is no response to the HTTP/2 request, it is unlikely that the request actually made it.
