Private key and certificate mismatch
If you are seeing this error as you deploy the certificate,
Your certificate was not installed due to the error : system failure: XXXXX ERROR: Unmatching certificate (/opt/zimbra/mailboxd/webapps/zimbraAdmin/tmp/current.crt) and private key (/opt/zimbra/ssl/zimbra/commercial/commercial.key) pair. Error code: ZaCertWizard.prototype.installCallback...
you need to regenerate the CSR, which will create a new key, and submit it to the CA to get it signed. To do this, simply start the certificate installation again.
Note:This issues is specific to commercial certificates.
