My custom domain [assignmentmaster.com.my](http://assignmentmaster.com.my/) is using Netlify DNS.

Both [assignmentmaster.com.my](http://assignmentmaster.com.my/) and [www.assignmentmaster.com.my](http://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.
