Bug: Discord voice/WebRTC not working
Apologies, first issue - thought I'd post it here as people are migrating from FF and likely to encounter the same issue. Could be a misconfiguration or something else.
Symptom
- Open Discord
- Go to a voice channel
- Enable microphone permissions
- See rapid toggling between "No route" and "Connecting" in a loop
The troubleshooting guide doesn't seem to work: https://support.discord.com/hc/en-us/articles/115001310031-Voice-Connection-Errors

I would appreciate if mullvad posted a solution on their blog (or elsewhere) detailing how to fix the problem and what privacy/security/anonymity problems it could pose.
