The APNs certificate does not match the CSR. Provide the correct APNs file (.pem) or submit a new CSR.

Description

You may receive an error message when you try to register the APNs certificate if you did not upload the most recently signed CSR file from 
BlackBerry
 to the 
Apple
 Push Certificates Portal.

Possible solution

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.
