Downloading audio at runtime in WebGL Cloud Build

I'm using this functionality:

Code (CSharp):

1. private IEnumerator LoadMusicClipFromWeb(string url)
2. {
3.     WWW www = new WWW(url);
4.     while (www.progress < 1.0f)
5.         yield return new WaitForSeconds(0.1f);
6.  
7.     if (!string.IsNullOrEmpty(www.error))
8.     {
9.         Debug.Log(www.error);
10.     }
11.     else
12.     {
13.         AudioClip clip = www.GetAudioClipCompressed();
14.         webMusicClips.Add(url, clip);
15.         PlayMusic(clip);
16.     }
17. }

To play audio clips from the web. This works great in editor, and in a local WebGL build, and in a downloaded ZIP of the Cloud Build, but through the Cloud Build interface, I don't hear the music playing.

I've tried it with MP3, OGG, and both GetAudioClip() and GetAudioClipCompressed(). The url that I am requesting the music from has CORS set up properly.

Is it possible to do this on Cloud Build?

 

Solved!

For anyone experiencing this same issue, the audio clip must be hosted on https in order to download from Cloud Build, as Cloud Build runs on https.
