I can't connect via webRTC, I get /connectionstate=failed - webrtc

Question

On webrtc debugger I have this from pc1 (call start):
From pc2 (join call):
Have error:
url: stun:54.166.135.129%C2%A0:443
address: 192.168.1.x
port: 59351
host_candidate: 192.168.1.x:59351
error_text: STUN host lookup received error.
error_code: 701
This is code for START CALL:
const startCall = async () => {
sendUser();
localStream = await navigator.mediaDevices.getUserMedia({
video: {
frameRate: 7,
width: 320,
height: 240,
aspectRatio: 1.33333,
},
audio: true,
});
localVideoRef!.current!.srcObject = localStream;
let configuration = {
iceServers: [
{ urls: 'stun:54.166.135.129:443' },
{ urls: 'turn:54.166.135.129 :443', credential: 'user', username: '123' },
],
};
peerConn = new RTCPeerConnection(configuration);
remoteStream = new MediaStream();
// Push tracks from local stream to peer connection
localStream.getTracks().forEach(function (track) {
peerConn.addTrack(track, localStream);
});
// Pull tracks from remote stream, add to video stream
peerConn.ontrack = (event) => {
event.streams[0].getTracks().forEach((track, index) => {
console.log(`REMOTE TRACK ${index + 1}: `, track);
remoteStream.addTrack(track);
});
console.log(remoteStream);
};
peerConn.onicecandidateerror = function (error) {
console.error('On ICE Candidate Error:', error);
};
peerConn.onsignalingstatechange = function (event) {
console.log('Signaling state change:', peerConn.signalingState);
};
peerConn.oniceconnectionstatechange = function (event) {
console.log('ICE connection state change:', peerConn.iceConnectionState);
if (peerConn.iceConnectionState === 'failed') {
console.error('ICE connection failed');
}
};
remoteVideoRef!.current!.srcObject = remoteStream;
peerConn.onicecandidate = (e) => {
if (e.candidate == null) return;
sendData({
type: 'store_candidate',
candidate: e.candidate,
});
};
await createAndSendOffer();
};
const createAndSendOffer = async () => {
const offer = await peerConn.createOffer();
await peerConn.setLocalDescription(offer);
sendData({
type: 'store_offer',
offer: offer,
});}
function sendData(data: { type?: string; candidate?: RTCIceCandidate; offer?: any; id?: string }) {
data.id = id;
console.log('SEND DATA: ', data);
webSocket.send(JSON.stringify(data));
}
function handleSignallingData(data: {
type: any;
answer: RTCSessionDescriptionInit;
offer: RTCSessionDescriptionInit;
candidate: RTCIceCandidateInit | RTCIceCandidate;
}) {
switch (data.type) {
case 'answer':
console.log('ANSWER:', data.answer);
peerConn.setRemoteDescription(new RTCSessionDescription(data.answer));
break;
case 'offer':
console.log('OFFER:', data.offer);
peerConn.setRemoteDescription(data.offer);
createAndSendAnswer();
break;
case 'candidate':
peerConn.addIceCandidate(new RTCIceCandidate(data.candidate));
console.log('CANDIDATE:', data.candidate);
}
}
This is code for JOIN CALL:
webSocket.onmessage = (event) => {
handleSignallingData(JSON.parse(event.data));
};
function handleSignallingData(data: {
type: any;
answer: RTCSessionDescriptionInit;
offer: RTCSessionDescriptionInit;
candidate: RTCIceCandidateInit | RTCIceCandidate;
}) {
switch (data.type) {
case 'answer':
console.log('ANSWER:', data.answer);
peerConn.setRemoteDescription(new RTCSessionDescription(data.answer));
break;
case 'offer':
console.log('OFFER:', data.offer);
peerConn.setRemoteDescription(new RTCSessionDescription(data.offer));
createAndSendAnswer();
break;
case 'candidate':
peerConn.addIceCandidate(new RTCIceCandidate(data.candidate));
console.log('CANDIDATE:', data.candidate);
}
}
function sendData(data: { type?: string; candidate?: RTCIceCandidate; answer?: any; id?: any }) {
data.id = chatUserId;
console.log('SEND DATA: ', data);
webSocket.send(JSON.stringify(data));
}
const joinCall = async (stop?: boolean) => {
localStream = await navigator.mediaDevices.getUserMedia({
video: {
frameRate: 10,
width: 320,
height: 240,
aspectRatio: 1.33333,
},
audio: true,
});
// Let's check if we have current. I have few times exception here
if (!localVideoRef!.current) return;
localVideoRef!.current!.srcObject = localStream;
let configuration = {
iceServers: [
{ urls: 'stun:54.166.135.129:443' },
{ urls: 'turn:54.166.135.129 :443', credential: 'user', username: '123' },
],
};
peerConn = new RTCPeerConnection(configuration);
remoteStream = new MediaStream();
// Push tracks from local stream to peer connection
peerConn.ontrack = (event) => {
event.streams[0].getTracks().forEach((track, index) => {
console.log(`REMOTE TRACK ${index + 1}: `, track);
remoteStream.addTrack(track);
});
console.log(remoteStream);
};
peerConn.onicecandidateerror = function (error) {
console.error('On ICE Candidate Error:', error);
};
peerConn.onsignalingstatechange = function (event) {
console.log('Signaling state change:', peerConn.signalingState);
};
peerConn.oniceconnectionstatechange = function (event) {

if (e.candidate == null) return;
sendData({
type: 'send_candidate',
candidate: e.candidate,

};
sendData({
type: 'join_call',
});
};
const createAndSendAnswer = async () => {
const answer = await peerConn.createAnswer();
await peerConn.setLocalDescription(answer);
sendData({
type: 'send_answer',
// #ts-ignore
answer,
});
};
We have a stun and turn server and we don't understand the problem.
