WebRTC connection fails when camera is off in Firefox and running vite server

[danielboxer]

• After switching to Vite instead of Create React App, (see 38aa44e), when joining a room in Firefox and the camera (and mic) is off, WebRTC connection fails.
• Error message is "WebRTC: ICE failed, your TURN server appears to be broken, see about:webrtc for more details"
• After 1 minute, error message "Media connection failed or Media activity ceased" shows
• If camera is on, there is no error
• It only happens when running vite dev server
