SSL certificate stuck at provisioning for custom domain seohamoon.com (DNS verification successful)

Hi, my site silver-basbousa-2731ab.netlify.app has a custom domain seohamoon.com (registrar: Gabia, using Netlify DNS with nameservers dns1-4.p08.nsone.net).

The dashboard shows “DNS verification was successful” and I have also clicked “Retry DNS verification”, but the site is still serving the default *.netlify.app certificate, so https://seohamoon.com does not work with its own certificate yet.

What I have checked: apex and www both resolve to Netlify’s load balancers, there are no CAA records on the domain, and there are no conflicting AAAA records.

Could you take a look and trigger the Let’s Encrypt certificate provisioning for this site? Thanks!
