SSL certificate cannot be provisioned for pro-line.kg

Site: prolinewebapp.netlify.app
Custom domain: pro-line.kg
Additional domain: www.pro-line.kg

I am using Netlify DNS with the four assigned nameservers:
dns1.p04.nsone.net
dns2.p04.nsone.net
dns3.p04.nsone.net
dns4.p04.nsone.net

The registrar is correctly delegated to these nameservers. Both pro-line.kg and www.pro-line.kg resolve successfully worldwide.

There is no DNSSEC/DS record configured and no conflicting AAAA or CAA record visible in my Netlify DNS zone.

I ran Let’s Debug for both pro-line.kg and www.pro-line.kg, and both report “All OK! No issues were found.”

However, Netlify still displays:
“We could not provision a Let’s Encrypt certificate for your custom domain.”

I also previously received “Request failed (429)” after attempting DNS verification.

The domain has been configured with Netlify DNS for approximately 9 days. Could you please check the certificate provisioning state for this site?
