Hi Netlify team,
My site is studioallestero.netlify.app with custom domain studioallestero.com (with www.studioallestero.com). DNS is managed externally at Cloudflare, not Netlify DNS.
My wildcard SSL certificate expires July 15, 2026 (already expired as of now). I am getting this error:
SniCertificate::CertificateValidationError: Unable to verify challenge for *.studioallestero.com: DNS problem: NXDOMAIN looking up TXT for _acme-challenge.studioallestero.com
I confirmed my A records in Cloudflare are set to DNS only (proxy disabled), pointing directly to Netlify’s servers. I clicked “Renew certificate” after confirming this, and it failed again with the same NXDOMAIN error. The “Renew certificate” button then disappeared again, leaving only “Set custom certificate.”
I do not need a wildcard certificate — I only use the apex domain and www subdomain, no other subdomains. Please remove the wildcard certificate requirement and issue a standard certificate covering studioallestero.com and www.studioallestero.com.
The site is currently down for visitors due to the expired certificate. I’d really appreciate urgent help with this. Thank you.
