Jellyfin on Roku

[RMikeS]

Roku can't find the Jellyfin server, even if I type the URL in by hand. Is this a common problem or am I just too dense to be able to figure this out? The server seems to be up and running on the desktop I installed it on, as it is available in the system tray. I've tried several variations on the URL, none work.

Does anyone here have an idea what to do?

I've cataracts and they make reading is a huge problem, so searching the docs hasn't been any help. Can anyone give me a leg up?

The IP address of the desktop is XXX.XXX.1.3, so my first try was:
XXX.XXX.1.3:8096

I've copied the address in my browser and input it with no joy. This is that address:
http://localhost:8096/web/index.html#/dashboard/tasks
I've tried that in it's entirety and I've tried it as just:
http://localhost:8096

I have a huge video collection. I've been watching it on Roku via the Roku Media Player for forever but it won't even give me a thumbnail, just the comment embedded in the file properties. I was delighted when I found the Jellyfin app on the Roku and have been salivating over thought of having all the metadata available as well.

Thanks for what ever help you can provide.
