This error above is a common issue that occurs when there is a pre-existing DNS record or domain. To resolve this issue, check the DNS zone of the corresponding primary domain and see if there is a DNS record already added for the addon domain or subdomain that you are trying to add.
- If a DNS record exists, you cannot add the new domain until you remove the record and the DNS zone’s corresponding entries.
- If a DNS record does NOT exist, make sure there is not a subdomain present and related to the same name in your cPanel.
- If no subdomain exists, but a DNS entry exists, it’s probably a remnant of any previous domain management activity. Remove the DNS entry and try adding your new domain again.
