I’m encountering the following issue when trying to get a certificate for my DNSSEC signed domain (greenhat.ch).
acme: Error 0 - urn:acme:error:connection - DNS problem: SERVFAIL looking up A for laki.greenhat.ch
When trying to issue the certificate on the same server for another, non-dnssec signed record it works perfectly fine, so my conclusion is that there is something off with the DNSSEC resolution of the Let’s Encrypt ACME backend.
I’ve checked through the several DNS related issues here, but did not fine anything which is solely related to DNSSEC. Are you aware of any issue related to DNSSEC?
Thanks for your help.
