Hostname already has externally managed DNS records, use 'override_existing_dns_record' to override?

Hostname 'mysiteredacted.org.country' already has externally managed DNS records (A, CNAME, etc). Either delete them, try a different hostname, or use the option 'override_existing_dns_record' to override. [code: 100117]
