Let's Encrypt certificate provisioning fails although DNS verification and Let's Debug are OK

Hello Netlify Support,

I’m unable to provision a Let’s Encrypt SSL certificate for my custom domain.

Netlify site:
seribusatu.netlify.app

Custom domain:
seribusatu.my.id

www domain:
www.seribusatu.my.id

DNS provider:
Rumahweb (External DNS)

DNS configuration:

A:
seribusatu.my.id → 75.2.60.5

CNAME:
www.seribusatu.my.id → seribusatu.netlify.app

I have verified the following:

  1. DNS is fully propagated globally using DNSChecker.
  2. A record resolves correctly to 75.2.60.5.
  3. www CNAME resolves correctly to seribusatu.netlify.app.
  4. There are no AAAA records.
  5. There are no CAA records.
  6. Netlify’s “Verify DNS configuration” succeeds.
  7. Let’s Debug using HTTP-01 returns “All OK”.
  8. The domain is correctly served by Netlify over HTTP.

However, Domain Management → HTTPS still shows:

“We could not provision a Let’s Encrypt certificate for your custom domain.”

Could you please check the certificate provisioning state for my domain and manually reset/re-provision the Let’s Encrypt certificate if necessary?

Thank you.
