MDM - APNs Mismatch!

Problem

You are trying to upload the APNs (MDM_ZOHO_Corporation_Certificate.pem) file, that you have downloaded from the Apple website in the Desktop Central server and you get an error message "APNs Mismatch"

Cause

While creating APNs certificate, you will have to download the Vendor Signed CSR from the Desktop Central server and upload it in the Apple website to download MDM_ZOHO_Corporation_Certificate.pem. After downloading the MDM_ZOHO_Corporation_Certificate.pem file, it needs to be uploaded in the Desktop Central server. If the Vendor Signed CSR does not match with the downloaded APNs certificate, then you might get this error.

Resolution

You need to verify if the most recently downloaded "Vendor Signed CSR" is uploaded in the Apple Push Notification portal to generate APNs.

In case you have downloaded the "Vendor Signed CSR" more than once, follow the steps mentioned below:

1. Upload the last downloaded "Vendor Signed CSR" again in the Apple Push Notification Portal.
2. Re-generate the APNs certificate.
3. Upload the re-generated APNs certificate on Desktop Central.

Note: If you have more than one Vendor Signed CSR, it is recommended to delete them all and restart the process, so that you can download a fresh Vendor Signed CSR and upload it in the Apple Portal to generate the appropriate APNs certificate.
