When attempting to add an addon domain in a cPanel account, you receive an error similar to the following.
"subdomain.domain.tld" is already a dynamic DNS domain. Because this domain is a subdomain of “domain.tld”, you cannot create a DNS zone with that name.
When an addon domain is created, a subdomain of the account's primary domain is created that the addon domain is parked on. The error occurs if the new subdomain has already been added as a Dynamic DNS domain. To add the domain, the Dynamic DNS domain must be removed first.
- Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
- Locate the Dynamic DNS ID.
[root@server ~]cPs# ls /var/cpanel/webcalls/user/$pausername/Please note that "$cpusername" must be replaced with the cPanel user's username.
- Use the UAPI to delete the Dynamic DNS domain.
[root@server ~]cPs# uapi --user=$cpusername DynamicDNS delete id='$ddnsid'Please note that "$cpusername" and "$ddnsid" must be replaced with the cPanel user's username and the Dynamic DNS ID.
