Nextcloud Talk: Video does not work on mobile (IOS + Android)


Here is the scenario:

  1. PCa in network X to PCb in network Y: Audio+Video works.
  2. PCa in network X to MOBILE in network X: Audio+Video works.
  3. PCa in network X to MOBILE in network Y: Audio works, Video works only from PC to mobile

In 3) the PC only sees a black screen while the video from the PC is displayed fine on mobile.

This happens with MOBILE beeing an IOS device with the IOS talk app and MOBILE beeing an android device with the android talk app.

Any ideas?

Kind regards!

Which browser on your PC ?

Firefox it is.

Have you tried with a chromium-based browser ? I know Firefox has some problems with video streaming.

Maybe same problem as here:
