The error Code: 1049 means the domain isn’t registered, the domain has no name servers, the domain name servers can’t be resolved, or the domain name servers don’t contain any DNS records and as a result the domain cannot be added to Cloudflare.
Verify the domain is registered, run a whois command to verify if the domain is valid, $ whois example.com.
Move to a different DNS provider prior to adding your domain to Cloudflare.
