My domain is: desguacebizkaia.com.es I ran this command: certbot certonly --webroot -w /path/to/web/root -d desguacebizkaia.com.es,www.desguacebizkaia.com.es It produced this output: Failed authorization procedure. desguacebizkaia.com.es (http-01): urn:ietf:params:acme:error:dns :: DNS problem: S…

Something is wrong with the Register.com nameservers, but I’m not sure what. Similar results from other domains sharing those nameservers (dns1.register.com, dns2.register.com): 123seek.com - https://acme-staging-v02.api.letsencrypt.org/acme/authz-v3/15330497 reinventions.net - https://acme-st…

DNSViz also thinks they’re often failing to respond: https://dnsviz.net/d/desguacebizkaia.com.es/dnssec/ It also notices that the domain’s NS records are inconsistent. That won’t automatically break anything – assuming all six nameservers work – but it should be fixed.

Hi @denis.sh [image] denis.sh: My domain is: desguacebizkaia.com.es there is the same problem, seen in an older topic (this week). Different name servers. [es] Then checked manual D:\temp>nslookup -type=NS desguacebizkaia.com.es. fnicdos.rediris.es. desguacebizkaia.com.es nameserver = d…

Regarding the mismatching NS records, 123seek.com does not have that problem, but it still produces the SERVFAIL (alternating with timeouts). So there is something else going on, or at least, in addition to.

Maybe Register.com is using anycast and has regional issues? Or they have very enthusiastic rate limiting? Or there’s a routing issue with Let’s Encrypt or Register.com or an intermediate ISP?

Edit: Nevermind, I can’t read.

Seems like whatever issues were plaguing register.com yesterday are now gone - Let’s Encrypt can validate all the domains now.

Can confirm the issues we were having with register.com are gone, and were able to get Let’s Encrypt to validate.

Today we don’t have issues with obtaining Letsencrypt certificates for Register.com domains.
