Vercel SSL certificate generation stuck after initial NXDOMAIN error

Problem

I’m having trouble generating an SSL certificate for a custom domain. The domain was added while DNS was still propagating, which initially caused the certificate request to fail.

Current Behavior

The Vercel dashboard shows:

Failed to Generate Cert

Clicking Refresh does not trigger a new validation attempt. It appears the certificate generation may be stuck on the original failed validation state.

Error:

Failed to Generate Cert
http-01 challenge failed
DNS problem: NXDOMAIN looking up A for www.mindthehat.com

Environment

DNS has since been corrected and is now fully resolving globally.

Current DNS configuration:

@    A      216.198.79.1
www  CNAME  cname.vercel-dns.com

Global DNS checks now resolve correctly to Vercel edge IP ranges (64.29.x.x, 66.33.x.x, 76.76.x.x, etc.), and there are no NXDOMAIN responses from authoritative servers.

Question

Has anyone seen this before or is there a way to force a fresh ACME validation cycle without removing both the root and www domains?

Domain: mindthehat.com

The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for bonus points.

You can also use v0 to narrow down the possibilities.
