Issue: SSL/TLS certificate provisioning keeps failing with the error “We could not provision a Let’s Encrypt certificate for your custom domain.”

What I’ve already checked/done:

  • Using Netlify DNS (nameservers migrated from mijndomein.nl, migration completed and DNS verification succeeded in the domain management panel)
  • Removed the old AAAA record on the apex domain
  • No CAA record present
  • Checked with Let’s Debug (letsdebug.net) - no issues found
  • Checked DNS propagation on dnschecker.org - A record resolves correctly to 75.2.60.5 in most regions
  • Removed and re-added the custom domain in Netlify to force a fresh provisioning attempt - still fails
  • Discovered and fixed a build misconfiguration: publish directory was set to dist/client but the build actually outputs to dist. Fixed this in Build settings and triggered a fresh deploy, which now shows as “Published” successfully.
  • After the successful deploy, still clicked “Provision certificate” again - still fails
  • More than 24 hours have passed since DNS verification succeeded, well beyond the automatic retry window

Could someone please check server-side what might be blocking certificate issuance for this domain? Happy to provide any additional details needed.

Thanks in advance!
