I installed Jellyfin in Start9OS and went thru the setup. I installed Filebrowser as well in which I uploaded my media.
Followed the services guide for Jellyfin for ios app in which I input my .local address for jellyfin ios app but I keep getting “Could not connect to server”.
It’s difficult to go wrong with this. The first things that come to mind are the more general things… such as not having access to .locals generally… from not setting up the Root CA, to running a VPN client, to not being on the same network as the server.
As a first test, grab the Jellyfin, or File Browser URL and try to open them in Safari.
