Hi Netlify Support,
My site (custom domain: lairo.es) has a wildcard certificate (*.lairo.es, lairo.es) that repeatedly fails to renew via DNS-01, even though the _acme-challenge CNAME delegation to _acme-challenge.lairo.netlify.app is correctly configured and verified at the DNS level (Hostalia).
Error: SniCertificate::CertificateValidationError: Unable to verify challenge for *.lairo.es (alternating between NXDOMAIN and “No TXT record found”).
I do not use any wildcard subdomains — only lairo.es and www.lairo.es are served by Netlify. Could you please remove the wildcard requirement for this site and reissue a standard Let’s Encrypt certificate covering only lairo.es and www.lairo.es, so it can renew via HTTP-01 instead?
DNS configuration:
lairo.es. A 75.2.60.5
www.lairo.es. CNAME lairo.netlify.app.
Thank you!
