Flatpak version doesn't work

[K0-RR]

I have installed the Flatpak service and started it from the app launcher, opened https://web.stremio.com and it still says "Streaming server is not available.". The (transparent) stremio-service icon is visible in the tray.
I'm on openSUSE tumbleweed. Stremio is also a flatpak and the main app is running (is it necessary to run it manually or the service will start it automatically?)

Same issue here, on Arch Linux.

Stremio services install fine through flatpak or via AUR, and starts also fine, yet flatpak has no tray icon (AUR package has it).

Browser, though, says "Streaming server is not available", and when I try to play something like a torrent, for example, I can hear the sound, but the video remains black.

Process are running

ps ax | grep stremio 
68601 ? Sl 0:49 /usr/bin/plasma-discover /home/malevolent/Downloads/com.stremio.Service.flatpakref
70443 ? S 0:00 bwrap --args 39 sh -c /app/share/stremio-service/stremio-service -o ''
70456 ? S 0:00 bwrap --args 39 sh -c /app/share/stremio-service/stremio-service -o ''
70457 ? Sl 0:00 /app/share/stremio-service/stremio-service -o
70480 ? Sl 0:00 /app/share/stremio-service/stremio-runtime /app/share/stremio-service/server.js

and I can see even ports opened

ss -putan | grep stremio

I've tried on the same computer on a web browser (Firefox and Chrome) and in an Amazon Echo Show, with Silk Browser. In all of them the same issue: sound working, but black screen instead of video.
