HTTPS doesn’t work

My custom domain assignmentmaster.com.my is using Netlify DNS.

Both assignmentmaster.com.my and www.assignmentmaster.com.my are active and DNS verification is successful.
HTTP works, but HTTPS still returns NET::ERR_CERT_COMMON_NAME_INVALID.

Certificate provisioning has been pending for approximately 24 hours.
Could you please check and re-trigger/reset the Let’s Encrypt certificate provisioning state for my site assignmentmaster.netlify.app?

Site:
assignmentmaster.netlify.app

Custom domain:
assignmentmaster.com.my
www.assignmentmaster.com.my

Registrar:
WebServer.com.my

DNS:
Netlify DNS

Issue:

  • DNS verification was successful.
  • Netlify DNS is active (green check).
  • Domain uses the Netlify nameservers.
  • HTTP works.
  • HTTPS returns NET::ERR_CERT_COMMON_NAME_INVALID.
  • SSL Labs shows the server presenting the default *.netlify.app certificate instead of assignmentmaster.com.my.

The netlify.app subdomain works correctly over HTTPS.

Could someone please check whether the Let’s Encrypt certificate provisioning is stuck and re-trigger it for my custom domain?

Thank you.
