ICE failed on Firefox(Chrome and Safari work)

[mantou132]

webrtc 0.4.0
macOS 12.5.1
Firefox 106

ICE error occurs when I use Firefox to establish a WebRTC connection to the server

I found a similar question on pion, looking at the thread description, it seems to be a bug of pion, So is it also a problem with webrtc-rs?

[k0nserv]

Yes that seems likely, although I've not experienced it with Firefox myself. What kind of ICE configuration are you using(lite, UDP mux, etc.)?

[mantou132]

@k0nserv

maybe UDP

https://github.com/mantou132/nesbox/blob/master/packages/server/src/voice/mod.rs#L110-L119

[k0nserv]

Hmm, I'm running with UDP muxing turned on, which is probably what you want for a server anyway.

See:

• https://docs.rs/webrtc/latest/webrtc/api/setting_engine/struct.SettingEngine.html#method.set_udp_network
• https://docs.rs/webrtc-ice/0.6.5/webrtc_ice/udp_network/enum.UDPNetwork.html

I tried Ephemeral and Muxed without effect.

It seems to be other reasons. I returned to the default settings, Firefox Log:
