Creating CNAME for custom url configuration is failing with "Cannot create CNAME record at the APEX domain"

KB Summary by Now Assist

Issue

For configuring ServiceNow custom URL one of the basic requirements is to create a CNAME on the DNS that points to the instance.

Creating the CNAME is failing with "Cannot create CNAME record at the APEX domain"

Cause

CNAME cannot be created at the root/apex of a domain, for example: myservicenow.com 

Resolution

As seen in the documentation the customurl should be of the format servicenow.acme.com and not acme.com, the fully qualified domain name (FQDN) of the custom URL.

Note: For example, servicenow.acme.com is the FQDN of the https://servicenow.acme.com URL.
