Change subdomain and now cant fix SSL certificate

SSL is working fine, but I made a change to point to a different subdomain using the Domain Management interface (let’s say from abc.--.com to def.--.com), and now I am unable to get the SSL activated on def.site.com.

def.–.com doesn’t appear to be served by Netlify

We can’t renew your Let’s Encrypt certificate automatically until the issue is resolved. Check our troubleshooting guide for more information on how to fix the problem, and then renew the certificate.

This is the domain in question: datasheets.netlify.app, and now it has the following configuration under SSL with no way to edit:

Certificate
Let’s Encrypt

Domains
abc.--.com

Created

How do i remove this SSL on this domain, and then add the correct one (def.--.com instead of abc.--.com)?

Thank you!

Hi, I just want to confirm is your DNS managed by us?
