Hi,
I already read https://www.digitalocean.com/community/questions/set-my-droplet-to-be-a-subdomain-of-a-domain-hosted-on-a-different-server but I have more questions.
I have a droplet that I want it to respond to requests made to a subdomain sucha as subdomain.domian.com
domain.com is hosted elsewhere, so name servers are not DO’s, but are the name servers of the hosting provider.
I named the droplet with FQDN, so PTR record exists.
I created the A record at the hosting DNS manager, pointing to droplet IP. That was 21 hours ago. I guess that is enough time for propagation, specially if no name servers were changed.
“# host subdomain.domain.com ns1.digitalocean.com” returns 5 (refused)
I don’t know if a have to add a domain to the droplet even if the name servers are not DO’s. No tutorials or community questions answer this.
So I added the domain to the droplet, and changed the NS records to point to the hosting name servers. Don’t know if this requires propagation time as well. I did this 2 hours ago.
“# host subdomain.domain.com ns1.digitalocean.com” now returns 3 (NXDOMAIN). Same result if using the hosting name servers.
The droplet already has an nginx server running.
I already powered off and on the droplet.
Don’t know what is missing or incorrect.
Please help.
Best Regards.

When adding an A entry, it should look something like:
A sub DROPLET_IP
Once the sub-domain A entry exists, you’d need to setup a proper server block for the sub-domain by either modifying the default server block or creating a new one, then restart NGINX for the changes to take.
The default server block for NGINX can be found here:
/etc/nginx/sites-available/default
Within the above file, you’ll see server_name, which what you’d modify.
server_name sub.domain.com www.sub.domain.com;
You’ll also want to modify root to tell NGINX where to find the files you’re uploading and want to use for the sub-domain.
Beyond that, what else needs to be modified depends on what you’re trying to setup (PHP, NodeJS, Python, etc).
