You cannot renew it with a different Apple ID, such as a newly created one.
Aside from cases such as a network problem that prevents you from logging in to the Apple Push Certificates Portal, if you cannot upload the CSR file (a certificate signing request file with the "csr" extension) or cannot download the Push certificate, your browser may not be supported.
Check \[ SETTING > Unit Detail > Apple > Apple ID Note \] in the admin console.
To renew the certificate, you must use the Apple ID that you used when you first registered the Push Certificate.
When the certificate expires, communication between the server and devices is lost, and you can no longer manage devices from the admin console at all.
