Scenario: Sometimes we get a request from the Customer to when requesting a certificate via API https://secure.comodo.com/products/!decodeCSR and gets an error -4 Unregistrable Domain Name!

The CN is 100% legit, FQDN and registered domain name, so why this strange message about the wrong domain name?
In this case, we need to email DBA with the required details below to override the domains from the Public Suffix list.
