i trying establish p2p audio/video connection b/w 2 peers. following: getting started webrtc.

it works fine @ home in lan environment between 2 pcs, throws error message when running @ company's lan environment, there part javascript

function processsignalingmessage(message) {         var msg = json.parse(message);          if (msg.type === 'offer') {             // callee creates peerconnection             if (!initiator && !started)                 maybestart();              // know jsep version after createpeerconnection().             if (isrtcpeerconnection)                 pc.setremotedescription(new rtcsessiondescription(msg));             else                 pc.setremotedescription(pc.sdp_offer,                         new sessiondescription(msg.sdp));              doanswer();         } else if (msg.type === 'answer' && started) {             pc.setremotedescription(new rtcsessiondescription(msg));         } else if (msg.type === 'candidate' && started) {             var candidate = new rtcicecandidate({                 sdpmlineindex : msg.label,                 candidate : msg.candidate             });             pc.addicecandidate(candidate);         } else if (msg.type === 'bye' && started) {             onremotehangup();         }     }

when first user recieved message "type":"candidate",get wrong

and part of console log:

  • creating peerconnection
  • created webkitrtcpeerconnnection config "{"iceservers":[{"url":"stun:stun.l.google.com:19302"}]}"
  • adding local stream
  • sending answer peer
  • recieved message : {"type":"candidate","label":0,"id":"audio","candidate":"a=candidate:1613033416 1 udp 2113937151 192.168.1.233 56946 typ host generation 0\r\n"}
  • uncaught syntaxerror: failed execute 'addicecandidate' on 'rtcpeerconnection': ice candidate not added
  • recieved message : {"type":"candidat".......}
  • uncaught syntaxerror: failed execute 'addicecandidate' on 'rtcpeerconnection': ice candidate not added
  • recieved message : {"type":"candidat".......}
  • uncaught syntaxerror: failed execute 'addicecandidate' on 'rtcpeerconnection': ice candidate not added

i think can create ice candidate message using msg.candidate,

var candidate = new rtcicecandidate(msg.candidate);

and pass addicecandidate function
