Hi Rhythm, I’m not an expert in reading Janus logs, but I noticed two differences in the logs you provided.
- In the Chrome log I see two ICE candidates from Janus, one for 192.168.x.x and one for 43.224.x.x.x. But in the Firefox log I only see the non-routable ICE candidate for 192.168.x.x. This would explain why ICE connection can’t get established. I would recommend to find out why in the Firefox case there is no public IP ICE candidate. - In the Chrome log I see a local SDP (sips -> local) and remote SDP (spds -> remote). But in the Firefox log the remote SDP is missing. Without the remote SDP the ICE connection and DTLS won’t get established. This is the first problem I would try to debug/solve.
