I'm having some problems with WebRTC in Chrome and so checked ICE Trickle test (stun:stun.l.google.com:19302 server).

It is not working in Chrome with no candidates being generated but working fine with Firefox with generated host and srflx candidates.

I'm using Chrome Version 81.0.4044.138 (Official Build) (64-bit) in macOS Mojave (10.14.6).

Can this problem be related to my local network? If so, how can I find the problem? Or is it related to any known recent problem with Chrome?

UPDATE: Firefox gather candidates:

I wrote test code. Chrome And Firefox is not collect srflx.

(async _ => {
  const pc = new RTCPeerConnection({iceServers:[{urls:['stun:stun.l.google.com:19302']}]});
  pc.onicecandidate = evt => {
    if(evt.candidate) {
      list.textContent +=(`${JSON.stringify(evt.candidate).match(/ typ (.+?) /, '$1')[1]}\r\n`);
    } else {
      list.textContent += '\r\<<END>>';
    }
  };
  const offer = await pc.createOffer({offerToReceiveVideo: true});
  await pc.setLocalDescription(offer);
})()
