Troubleshooting: APNs

Problem
Possible solution
When you try to obtain a signed CSR, you get the following error: "The system encountered an error. Try again."
When you try to register the APNs certificate, you receive the error "The APNs certificate does not match the CSR."
If you downloaded multiple CSR files from
BlackBerry
, only the last one that you downloaded is valid. If you know which CSR is the most recent, return to the
Apple
 Push Certificates Portal and upload it. If you are not sure which CSR is the most recent, obtain a new one from
BlackBerry
, then return to the
Apple
 Push Certificates Portal and upload it.
You cannot activate
iOS
 or
macOS
 devices.
The APNs certificate may not be registered correctly. Check the following:
  • In the management console, on the menu bar, click
    Settings > External integration > Apple Push Notification
    . Verify that the APNs certificate status is "Installed." If the status is not correct, try to register the APNs certificate again.
  • Click
    Test APNs certificate
     to test the connection between
    BlackBerry UEM
     and the APNs server.
  • If necessary, obtain a new signed CSR from
    BlackBerry
     and a new APNs certificate.
