Expose a virtual host on a separate TCP port that uses the PROXY
protocol. This way, HAProxy can pass the original client IP address to
Jellyfin without terminating the TLS connection.
Since Jellyfin is running on the file server, which also hosts a few
other websites that do not define virtual hosts, the HTTP-to-HTTPS
redirect was applied to *all* requests. To avoid this, we simply add a
rewrite condition so that the redirect only applies to requests for
Jellyfin.
Jellyfin is a multimedia library manager. Clients can browse and stream
music, movies, and TV shows from the server and play them locally
(including in the browser).
