difference between nginx and ddns service

[Drake97]

It's been a long time since I've done this process.  I had to re-read the guides I used.  It looks like you CANNOT have any https configs, period.

Remove all https servers, you only need a server config listening on port 80.  Run the certbot setup and it will acquire the certificates.  THEN you setup your https configs.

I managed to make it work, I had to change the port of use of pihole and leave the 80 for all the nginx config, besides, I had to acquire a ddns to put in my domain.
I did the steps, I downloaded a certificate, the file /etc/nginx/sites-enabled/jellyfin was left with the new certbot config, however when I put my ddns.net:8096 it does not redirect me to jellyfin with HTTPS, but when I put ddns.net:80 it redirects me to the nginx home with HTTPS, in jellyfin it stays as HTTP.

I have to do one more configuration ? in my router I have open TCP ports 80 and 443 and 8096 in TCP/UDP.
In the jellyfin configuration should I enable something else?

thanks in advance
