You can check the connectivity between Workspace ONE UEM powered by AirWatch and the Apple HTTP/2 API endpoint. This check allows you to ensure APNs functionality over an HTTP/2 connection after generating a new certificate or following a certificate renewal.

Prerequisites

This connectivity test is only for testing APNs over HTTP/2 which is not enabled by default. Any connectivity failures from this test do not impact APNs functionality over a legacy connection.

Procedure

  1. Navigate to Groups & Settings > All Settings > Devices & Users > Apple > APNs for MDM.
  2. Select the Test Connection button.
    The Workspace ONE UEM console conducts an internal test to determine whether connectivity over the new HTTP/2 protocol is functional.

Results

Because this test only centers on the HTTP/2 protocol, test failures here do not affect current APNs communication. If the HTTP/2 connectivity test fails, the steps you take depend upon the cause of the failure.

  1. Expired Certificate - The certificate you are using for the test has expired. Request a renewal by viewing Renew an APNs Certificate.
  2. Invalid Certificate - The certificate you are using for the test, while not expired, is invalid for another reason. You can request a certificate renewal or wait a few minutes and test the connection again.
  3. Unknown Error - Typically occurs during a temporary loss of Internet access. Wait a few minutes and test the connection again.
  4. APNs Client Deactivated - While rare, this cause means that Apple has returned an internal error or that the APNs service is unavailable. Wait a few minutes and test the connection again.
