How do I access local host on other devices?

[Farnsworth]

Sometimes my internet is slow so I get buffering with Jellyfin. This isn't a problem when watching content directly from my server though. I'd really like to have it so that any device connected to the same home connection as my server could just use the local host like my server can.

I'm wondering if this is possible without my devices being connected via ethernet. I'd like to being able to run the local host right off my android TV Jellyfin app that's on my firestick.
