LTE to WIFI connections not working for WebRTC connection but Wifi to Wifi does

I’m writing a video chat application and I’m currently using google’s public STUN server and making request to xirsys’ endpoint for remote TURN servers. When I look at the logs I noticed bag tcp packets are being sent with devices using LTE connection and udp packets being sent with devices using WiFi connection. At first, I assumed that the issue was that I was only using STUN servers instead of both TURN and STUN servers. However, I’m still getting “data.sdp is undefined” and/or the icestateconnection is stuck in the state of “checking.” Can someone please not only review and analyze the code and it’s fallacies but explain why this is occurring and provide any resources you know to help my understanding of the issue. Thanks!

[code]

//fetch for ice servers
if (servers) {
  console.log(`servers: ${JSON.stringify(servers.v.iceServers, null, 2)}`);
  iceServers = [
    ...servers.v.iceServers,
    {"url": "stun:stun.l.google.com:19302"},
    {"url":'stun:stun1.l.google.com:19302'},
    {"url":'stun:stun2.l.google.com:19302'},
    {"url":'stun:stun3.l.google.com:19302'},
    {"url":'stun:stun4.l.google.com:19302'},
  ];
  return;
}

//configuration
pc = new RTCPeerConnection({"iceServers": iceServers};);

//exchange to signaling server
exchange(data) {
const fromId = data.from;

if (!pc)
  this.createPC(fromId, false);

console.log(`Data: ${JSON.stringify(data, null, 2)}`);
console.log(`Data.sdp ${data.sdp}`);
if (data.sdp) {
  console.log('exchange sdp', data.sdp);
  pc.setRemoteDescription(new RTCSessionDescription(data.sdp), function () {
    if (pc.remoteDescription.type === "offer")
      pc.createAnswer(function(desc) {
        console.log('createAnswer', desc);
        pc.setLocalDescription(desc, function () {
          console.log('setLocalDescription', pc.localDescription);
          socket.emit('exchange', {'to': fromId, 'sdp': pc.localDescription });
        }, logError);
      }, logError);
  }, logError);
} else {
  console.log('exchange candidate', data);
  pc.addIceCandidate(new RTCIceCandidate(data.candidate));
}

}

Turns out that I initiated my configuration for the ICE Servers before my servers were set after a network request! Problem solved!
