I'm setting up a new educational website (eiremaths.ie) for a Leaving Cert Maths course business and cannot get the SSL certificate to provision despite DNS being fully verified and working

Site name: sparkly-cuchufli-4c8d2a.netlify.app
Custom domain: eiremaths.ie
Error: “We could not provision a Let’s Encrypt certificate for your custom domain”

Both eiremaths.ie and www.eiremaths.ie load correctly on http. Domain management shows green Netlify DNS ticks for both. DNS verification passes successfully when I click “Verify DNS configuration” — but immediately after, clicking “Provision certificate” returns instantly to the same error. This has happened multiple times over 24+ hours of automatic retries.

Troubleshooting done:

DNS is using Netlify DNS with nameservers set at registrar Blacknight. Everything on the DNS side appears correct. Could someone please force-provision the certificate from your end
