I use noip.com ddns service + luci-app-ddns to point a http(s)://something.ddns.net to my nextcloud vm and that works well. I'd like to do the same for my jellyfin vm (possibly for more machines I want to access from outside my lan in future), but I've no idea how to go about that / whether it's possible. So far no matter what I tried either outright doesn't work, or opens my nextcloud complaining about being tried to access from unauthorised hostname.
Would be absolutely ideal if I could just use my existing nextcloud vm ddns hostname (which already has letsencrypt certificate) just on different port, again no idea if this is possible or how to go about it.
Any suggestion welcome, thanks!
