Question

Can't get Let's Encrypt SSL to work on a NS subdomain

I’ve added NS record for a subdomain files.elevation-us.com

GoDaddy NS Records
GoDaddy NS Records

Also added the domain in DO domains with CNAME ‘ftp’ to nyc3.digitaloceanspaces.com digitalocean subdomain ssl That way I end up with ftp.files.elevation-us.com.

Finally, CDN was enabled with a wildcard SSL for *.files.elevation-us.com digitalocean subdomain ssl For some reason I can only select the wildcard and that’s why i need the additinal ftp part.

I’ve tried creating both the spaces/buckets to no avail. digitalocean subdomain ssl

The following works but the SSL is not working: https://ftp.files.elevation-us.com/test.png

The current SSL used is for *.nyc3.digitaloceanspaces.com

I’m stuck here. How do I get custom CDN subdomain to work with existing domain without transferring the entire NS to DO? If I don’t use NS and only CNAME I can’t issue certificate. If I do, the SSL doesn’t work even when it’s wildcard. (Ideally, i want only files.elevation-us.com but ftp.files… would work if it’s needed) The only thing that worked in the past is to route trough CloudFlare and use flexible SSL.

Hey,

Indeed, I’ve seen this issue before using a subdomain name along with NS records.

My workaround has been to use Cloudflare as you’ve mentioned already:

You could try reaching out to the DigitalOcean support team who might be able to assist you further with this:
