SSL certificate Custom domains

DNS verification is successful but SSL certificate is not provisioning for custom domain.
Browser shows ERR_CERT_COMMON_NAME_INVALID and serves wildcard netlify app cert for blinkboardz com.

What I already did:

  1. Switched nameservers to Netlify DNS (dns1/2/3/4 p04 nsone net)

  2. Added Netlify DNS records for apex and www pointing to the site

  3. Removed and re-added custom domains

  4. Retried DNS verification multiple times

Current status:

  • Netlify subdomain works

  • Custom domain HTTPS still fails

Request:
Please manually check and trigger SSL certificate issuance for blinkboardz com and www blinkboardz com.
