Will jellyfin 10.9.3 server work on Windows 8.1

[Bryan]

I don't want to upgrade my server OS to windows 10, 8.1 is working perfect, I only use it to file serve and run the Jellyfin server.
I wouldn't even upgrade my jellyfin server but when I log into the jellyfin app on my amazon firestick app I get a warning

Update your server from 10.8.8 to at
least 10.9.0 to continue using the app
after the next update.

I don't want to update the jellyfin app on my firesticks and firetv. I have 4 TV's with firesticks and one Fire TV, and my server OS is windows 8.1, everything works great as is.

Do I have to update the app?
If so, will the jellyfin server 10.9.3 work on windows 8.1?
