Firefox: ICE failed, add a STUN server and see about:webrtc for more details

Hi,
“ICE failed, add a STUN server and see about:webrtc for more details”
I got this error mostly of time in firefox72, whereas the same stream is played correctly in chrome.

I use mediasoup-client v2.4.10

Any clue why this happens only on firefox ? (I got this error reported many times)

You are not providing any info for just a error log. You may describe your topology, whether you are enabling UDP and TCP in mediasoup WebRTC transports or just UDP (Firefox does not implement WebRTC over TCP so that may explain that clients using Firefox in UDP-blocked networks may not connect to mediasoup. But I don’t know, you have provided zero info but just a log.
