and sudo netstat -npta | grep turnserver gives

i have generated the temporary username and password

val secretKey = "fb1d5d356dff13e709980e2a07dfcef130a713d53e4c6701efe4b770f27e17d4"
val userId= "abcd1234"
val ttl:Long = 3600 * 6
val unixTimeStamp =System.currentTimeMillis()/1000L + ttl
val userName = unixTimeStamp +":"+ userId
val secret = new SecretKeySpec(secretKey.getBytes, "HmacSHA1")
val mac = Mac.getInstance("HmacSHA1")
mac.init(secret)
val result: Array[Byte] = mac.doFinal(userName.getBytes)
val hashStr= new String(result.map(_.toChar))
val password = Base64.getEncoder.encodeToString(hashStr.getBytes())

and it produces the output username:1601663142:abcd1234 password: Wi4H776QJCoFbe+/hgrvv7Pvv5te77+m776L776K776N77+Y77+UUQ==

i have tested this in two ways first in chrome console following code throws the exception

var iceConfiguration = {
    iceServers: [
        {
            urls: 'turn:127.0.0.1:3478',
            username: '1601663142:abcd1234',
            credentials: 'Wi4H776QJCoFbe+/hgrvv7Pvv5te77+m776L776K776N77+Y77+UUQ=='
        }

    ]
}

var peerConnection = new RTCPeerConnection(iceConfiguration);

Uncaught DOMException: Failed to construct 'RTCPeerConnection': Both username and credential are required when the URL scheme is "turn" or "turns".

and Tricle Ice

how can i get it to working

Answer 1

I think the answer is simple, you've specified credentials and the error is that credential is missing, so remove the s and try again.
