Hello! I just installed jellyfin and wanted to access it with https. So, as I did yesterday for other apps (immich) in nginx proxy host I created a new proxy host, set the domain (jellyfin.mydomain.duckdns.org), set “create new SSL certificate”, “I agree on let’s encrypt stuff” and clicked save. Ports 80 and 443 are the only ports exposed on my router.

After some loading, internal error. searching on the web I tried the followings:

  • tried with and without “force SSL”
  • open port 81 on the router [source]
  • checked Use a DNS Challenge as explained here

but internal error was always there. Any idea what could be the problem? and why yesterday everything worked flawlessly?

EDIT: I rebooted and then i couldn’t even log in, bad gateway error. after some troubles I do not remember I achieved to log in, and now the SSL certificate has been added correctly!
