Hi, @rahul-sundaresan. If you are not using Netlify DNS then, yes, we must manually update the SSL certificate when new branch subdomains are added.
Note, I’m not seeing the branch subdomain DNS record for the primary custom domain here:
I do see a
beta subdomain for the root domain, but the root domain isn’t the primary custom domain.
Here is an example. If the primary custom domain is
example.com then the branch subdomain would be
If, however, the primary custom domain is
www.example.com (similar to this site) then the branch subdomain would be
Before we can update the SSL certificate we need the DNS record to be created following those guidelines. Please let us know when the record exists and we’ll extend the SSL certificate to cover it. If there are any questions or concerns, please let us know.
