I am running the latest
certbot and have been handling authentication via
acme-dns installed on a server I control, using
lexicon to manage entries…
I recently migrated approximately 30 domains onto Cloudflare’s platform, so I could renew the domains with Cloudflare as the registrar.
I did not plan the migration well, and did not pay enough attention during this process - I lost many (all?) of the DNS entries that handled my letsencrypt integration. I’ve got the acme-dns server available to letsencrypt, but I lost all(?) the CNAMEs redirects.
I’ve pored through the certbot logs looking for answers, and can’t seem to find the right debug lines. Can anyone point me in the right direction on what to look for? The
acme-dns installation is fine, so I don’t need to adjust that… I just need to figure out what CNAME redirects for each domain should be.
For example, I see the debug line:
FailedChallenges: Failed authorization procedure. example.com (dns-01): urn:ietf:params:acme:error:dns :: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.example.com
And I need to recreate the correct subdomain to cname onto acme-dns
