Hi Netlify Support,
My site is benevolent-torte-f5aaea.netlify.app and my custom domain is chemicalmechanix.com (with www.chemicalmechanix.com).
My DNS is managed externally at Namecheap (not Netlify DNS). The domain was originally set up on Netlify DNS, so a wildcard certificate (*.chemicalmechanix.com) was provisioned back in November 2025. I’ve since moved DNS to Namecheap and deleted the old Netlify DNS zone.
The certificate renewal is now failing with:
SniCertificate::CertificateValidationError: Unable to verify challenge for
*.chemicalmechanix.com: DNS problem: NXDOMAIN looking up TXT for
_acme-challenge.chemicalmechanix.com
This is expected — the wildcard requires a DNS-01 challenge that can’t be satisfied with external DNS. I do not need a wildcard; I only serve the apex and www.
Could you please remove the wildcard certificate requirement from this site and trigger a standard Let’s Encrypt certificate for:
validated via HTTP-01? My DNS is already correctly pointed at Netlify:
- A @ → 75.2.60.5
- CNAME www → benevolent-torte-f5aaea.netlify.app
Thank you for your help.
