I have a domain mydomain.com and I set up a subdomain (sub.mydomain.com) which has SSL certificate associated with it with a redirect configured from HTTP to HTTPS which points to a droplet on DO, DNS record is properly setup.
When I visit the link I get “no server IP address could not be found” or no data
licences.energycom.gov.gh is added on the droplet as a domain and when I try to install letsEncrypt SSL certificate using (https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-20-04) I get unable to install the certificate but the certificate and chain are stored. How do I correctly setup the droplet so I can install SSL and be able to serve the request and return data when accesses through the subdomain
What do I need to do for the droplet to serve the subdomain request with data,

Do you have a Nginx configuration file for port 80/HTTP for your subdomain?
It sounds like Nginx can’t find your subdomain as it’s configured on it. Check the following article on how to do it.
The preferred method for redirecting HTTP to HTTPS in Nginx is to set up a separate server block for each version of the site. You should avoid redirecting traffic by using the if policy, as it can cause unpredictable server behavior. Redirect HTTP to HTTPS per site.
You probably have a misplaced policy in subdomain configuration. Feel free to share your subdomain block.
