My custom domain is senau.music (and www.senau.music, listen.senau.music). My Let’s Encrypt certificate is stuck trying to renew as a wildcard (.senau.music), which fails with:*
*SniCertificate::CertificateValidationError: Unable to verify challenge for .senau.music: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.senau.music
My DNS is managed externally at Cloudflare, not Netlify DNS, so the wildcard DNS-01 challenge can’t be satisfied automatically. I don’t need a wildcard — only senau.music, www.senau.music, and listen.senau.music. How can I remove the wildcard requirement and reissue a standard Let’s Encrypt certificate for these specific domains?. My certificate expires September 6, 2026.
