Question
How do I address the following error?
Error: domain.tld. already has a CNAME record. You may not mix CNAME records with other records.
Answer
You are unable to mix Canonical Name (CNAME) records with other records because CNAME records are alias for other domain names or subdomain names, which are resolved by DNS. If you want to add a DNS record for a subdomain when a CNAME record for that subdomain exists, you must delete the CNAME record before attempting to add the new DNS record.
