@wookie_73 so you were redirecting from namecheap DNS to a special subdomain hosted cloudflare nameservers and it didn’t work?
Thinking about it, that’s probably because your subdomain might be something like ‘validation.domain.com’ and your cname ‘_acme-challenge.domain.com’ points to ‘_acme-challenge.validation.domain.com’ but our API calls are looking for ‘domain.com’ in the DNS zone that the API credentials have access to.
Interesting, we probably need an surrogate domain option so you can specify ‘_acme-challenge.validation.domain.com’ etc as the real target for the the TXT record.
