I am using @serverco’s getssl client to renew a certificate for one of my domains. However, the process is failing with “DNS problem: NXDOMAIN looking up TXT for _acme-challenge.s007.co”. I believe the issue is to do with the domain’s DNS being cached by the ACME servers, preventing it from issuing a certificate.
The domain is s007.co and the challenge is at https://acme-v01.api.letsencrypt.org/acme/challenge/KhSNr1OZenuCES20hfS8prR3SnwwL3iuh-_0ZVY_IBc/694042360.
This has been happening for the last few weeks and the current certificate has now expired.
Can someone please take a look at this?
