Check if DuckDNS can do CNAMEs. In DuckDNS you would setup a CNAME called "jellyfin", or whatever you want,that points to your DuckDNS domain name.
Then in Nginx you would change the "server_name" field to include your subdomain, jellyfin.domainname.duckdns.org. Once you've made that change, re-request your certificates. It should add your subdomain as a SAN (subject alternative name).
