Jitsi keep disconnecting on some networks

Hello @damencho @bbaldino,

Jitsi running on some xxx.xxxx.xxxx.xxxx server and working well with recording and other features on public networks ( Data pack or Broadband in India ). If we provide same URL to other clients (which is from some secure network and for accessing they need to whitelist the URL) to join the meeting they keep disconnecting without 5 to 10 second.

Error in browser console.
CONFERENCE : conference.iceFailed

To prevent these we enable enableIceRestart: true now user not disconnecting but they will freeze for some seconds like 10 to 20 sec and again play like well.

We use,
stunServers: [
{ urls: ‘stun:xxxx.xxx.xxxx.xx:4443’ },
{ urls: ‘stun:meet-jit-si-turnrelay.jitsi.net:443’ }
],

In video bridge configuration we’ve added, ( We don’t have aws server )

org.ice4j.ice.harvest.NAT_HARVESTER_LOCAL_ADDRESS=127.0.0.1
org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=< Public IP of the server>
org.jitsi.videobridge.NAT_HARVESTER_LOCAL_ADDRESS=127.0.0.1
org.jitsi.videobridge.NAT_HARVESTER_PUBLIC_ADDRESS=< Public IP of the server>
org.ice4j.ice.harvest.DISABLE_AWS_HARVESTER=true

Commented,
org.ice4j.ice.harvest.STUN_MAPPING_HARVESTER_ADDRESSES=meet-jit-si-turnrelay.jitsi.net:443

Thanks.
