EasyAR Cloud UnityWebrequest not return any response and process stuck at there,

Question

Hello,

i am using EasyAR Version : 3.0.1-final-r238a6316e  , EasyARCloud demo ,

Just add a simple script to instantiate object runtime when target detects and pass URL on that object script and call web request, but not getting any response and nothing happen.

I tried this script in a different scene and work perfect as aspected, but not working in EasyAR Cloud scene,

here is my instantiate code ..

var cube = Instantiate(Resources.Load("HelloAR_ImageTarget_Cloud/prefabs/AudioPlayer", typeof(GameObject)) as GameObject);
cube.GetComponent<AudioClipHandler>().url = data.contentURL;
 cube.transform.parent = go.transform;
 cube.GetComponent<AudioClipHandler>().StartAudio();

and here is my web request call on instantiate an object

    public void StartAudio()
    {
        Debug.Log("URL Set By CloudRecognize : " + url);
        StartCoroutine(GetAudio(url));

    }

    private IEnumerator GetAudio(string url)
    {
        Debug.Log("Start Call URL and Load AUdio ");

        using (UnityWebRequest www = UnityWebRequestMultimedia.GetAudioClip(url, AudioType.MPEG))
        {
            yield return www.SendWebRequest();

            if (www.isNetworkError)
            {
                Debug.Log(www.error);
            }
            else
            {
                AudioClip myClip = DownloadHandlerAudioClip.GetContent(www);
                source = GetComponent<AudioSource>();
                source.clip = myClip;
              
                if (source.clip != null)
                {
                    source.Play();
                    source.playOnAwake = true;
                }
            }
        }

}

But stuck after Web request not getting a response.
