Apple Push Notification Service Certificate Renewal


This how-to explains how to renew your Apple Push Notification Service certificate on a regular base. Since the Apple Push Notification Service certificate has a maximum validity period of 1 year, you will need one year after your first APNs certificate creation or one year after the last renewal, to renew the certificate in order to continue managing your Apple devices.

We recommend performing the renewal process with Chrome, Firefox or Microsoft Edge.

This FAQ should address frequent problems and challenges when creating or extending the Apple Push Notification Service certificate.

I get an an error message when I chose to let Silverback sign the request automatically. A web browser page pops up to Matrix42 Accounts error message "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."
This is most likely a problem with your Matrix42 Account permission. Please contact the Matrix42 support to correct the permission settings, or cancel the current request and start the process again and choose 'I will perform the signing by myself' as the CSR signing option.

Which Matrix42 Account permissions does an admin need to use the automatic Silverback request feature?
The admin needs 'Enterprise Manager' permission for his Matrix42 Account.

What can be the reason for a non-matching Apple APNS topic?
Typically this is because you used the wrong Apple ID. Cancel the current CSR request, and find out the correct Apple ID used for the initial APNS creation.
