Texture2D.LoadImage unable to parse bytes

Question

I'm downloading a raw byte array to be used as a Texture2D using a technique by at SO.

 UnityWebRequest www = UnityWebRequest.Get("myurl");
 
 DownloadHandler handle = www.downloadHandler;
 
 yield return www.Send();
 
 if (www.isNetworkError)
 {
 
     UnityEngine.Debug.Log("Error while Receiving: " + www.error);
 }
 else
 {
     UnityEngine.Debug.Log("Success");
 
     Texture2D texture2d = new Texture2D(8, 8);
 
     texture2d.LoadImage(handle.data);
                     
 }

LoadImage, however, can't parse the byte array and gives me 'red question mark' fallback.

So the issue was in LoadImage not being able to parse the image's header. The function starts reading the texture as a bytearray, however first encounters the header, and doesn't know what to do with it.

Furthermore, the image was hosted on an S3 bucket, which assigned a header by default. Removing the header on S3 solved the issue.
