[SOLVED] Can't connect to jellyfin-media-player from android app - it was a proxy config issue

so, up until recently (week or two maybe?) I was able to connect to the jellyfin-media-player from the jellyfin android app and initiate and control playback, change subtitles, the works. well, it's not there any more, when I click on "Play On" I can only connect to the jellyfin-mpv-shim instance, which works same as before.

now before I start troubleshooting and pulling stuff apart, can anyone chime in if it works for them?

edit: same thing when using the web client in firefox, isn't detected.
