cannot open port 443 (lemmy.one)

Hi. I want to start selfhosting my data. I already have a jellyfin server running. I'd like to add a nextcloud instance. The setup of nextcloud says I should open up port 443 for using my own domain. Sadly I am not able to open up this port properly. It is open however when I visit jellyfin.mydomaim.com it is rerouted to the config of my router. To circumvent this problem I have set up a reverse proxy that accepts port 8443 instead of 443. For my jellyfin this seems to work. I can visit it with jellyfin.my domain.com:8443. I don't know how I can get this to work for nextcloud as it only accepts 443. Any advice on my setup is welcome! BTW I am running Debian on an old PC.
Thanks in advance for the help!

If you are seeing your routers config page, and you are sure you are connecting from outside your network, it sounds like the router's 443 page is overriding the port forwarding. Otherwise, it's like @[email protected] said and you just need a local DNS that points to the right spot locally, and let your public DNS point for external connections.

As for the hosts file, you can see a guide here for windows/linux/mac. Basically this is a override of any DNS entries. Here you can point jellyfin.domain.com to your jellyfin servers LAN IP and test the connection works.
