Could not connect media

[endurable-remodeler-eleven]

Description

When trying to make a voice call I cannot connect to the other person. The call tries to connect then says "User ended the call. (could not connect media)". This is across the internet, not LAN.
If I connect to personal VPN from outside LAN, I can hear the other person who is inside the LAN but they cannot hear me.

Steps to reproduce

• Make a voice call from outside the LAN

Describe how what happens differs from what you expected.

Thanks for the report!

What happens if you try other WebRTC based apps using the same network connection as the one having the issue?

For example, you could try https://appr.tc/ or https://appear.in/.

(I am just trying to isolate if you see the same for any WebRTC based call, or Riot only.)

Same bug here. Both sides receive the "could not connect media" error. There seems to be a problem connecting via https://appr.tc/ as well. No LAN / VPN used.

Permissions for the web app to access web camera and microphone have been granted.

Firefox 66.0.3, Windows 10, riot.im/app

Then this seems to be an upstream issue, sorry.

Hi, I have the same issue as described above. Can anyone help to debug this problem? When calling people that are on the LAN it works fine. When I try cal someone from outside the LAN it fails with "could not connect media" error.

Thats what I get in my firefox console:
