Wildcard cert renewal fails - DNS problem NXDOMAIN (external DNS, stale Netlify DNS zone already removed)

Support

Site name: nureeff.netlify.app
Custom domain: nureeff.com

Issue: Wildcard certificate (*.nureeff.com) renewal is failing with:
SniCertificate::CertificateValidationError: Unable to verify challenge for *.nureeff.com: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.nureeff.com

My DNS is managed externally via Cloudflare (nameservers braelyn.ns.cloudflare.com / skip.ns.cloudflare.com), not Netlify DNS, so the DNS-01 challenge required for wildcard certs can’t be completed.

I found and deleted a stale, unused Netlify DNS zone that existed for this domain (all NETLIFY/CNAME/TXT records removed). The live site was unaffected throughout, confirming Cloudflare is the actual authority. After removing that zone, I retried “Renew certificate” but got the same NXDOMAIN error, then a “too many certificate creation attempts” rate-limit message, and now the same NXDOMAIN error again.

I don’t need a wildcard - I have a fixed, known list of subdomains. Could you please remove the wildcard certificate and reissue a standard Let’s Encrypt certificate covering these specific domains instead (using HTTP-01, which works fine through my current Cloudflare setup):

  • nureeff.com
  • www.nureeff.com
  • ai.nureeff.com
  • avia.nureeff.com
  • go.nureeff.com
  • note.nureeff.com
  • talk.nureeff.com
  • russian.nureeff.com

Thank you!
