Failed authorization procedure. dev.cristal-sons.be (dns-01): urn:ietf:params:acme:error:dns :: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.dev.cristal-sons.be
IMPORTANT NOTES:
- The following errors were reported by the server:
Domain: dev.cristal-sons.be
Type: None
Detail: DNS problem: NXDOMAIN looking up TXT for
_acme-challenge.dev.cristal-sons.be
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): 0.31.0-2.el7
I used this command since a long time without issue. It started today. I will try your suggestions : adding a greater TTL in command and the debug challenges option.
