HTTPS certificate cannot be renewed


I have an issue with a website I manage. The SSL/TLS certificate cannot be renewed. The error is SniCertificate::CertificateNonvalidError: Unable to verify challenge for 2001:bc8:4::2: Invalid response from 404. I had a very similar error last year.

Can you help figure out what are the next steps I should do?


Hey @alex-noima

It appears the DNS records for are not correct, thus the issue. As per the configure external DNS documentation the apex domain requires an ALIAS record pointing to the Netlify load balancer or A record pointing to the load balancer IP Currently the apex points to

% dig		14400	IN	A		14400	IN	A

The www subdomain is correctly configured.
