Extend External DNS Branch Subdomain SSL

Hi there, as per this help article: [Support Guide] How to use Netlify’s branch deploy feature without Netlify DNS

It’s recommended I contact support through the forums to get the SSL on my main site extended to my branch subdomain if I’m using external DNS.

Could I trouble someone to extend the SSL on


Hi @ColinTravis,

I can see that you already have a working SSL for dev.colintravis.com. What you’re asking for is dev.colintravis.netlify.app - this is not a valid domain. Netlify sets a branch as dev–colintravis.netlify.app, thus you can’t get the SSL as you describe.
