  <p>Any ideas why? Also I have CORS setuped as that:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"&gt;
  &lt;CORSRule&gt;
  &lt;AllowedOrigin&gt;*&lt;/AllowedOrigin&gt;
  &lt;AllowedMethod&gt;HEAD&lt;/AllowedMethod&gt;
  &lt;AllowedMethod&gt;GET&lt;/AllowedMethod&gt;
  &lt;AllowedMethod&gt;PUT&lt;/AllowedMethod&gt;
  &lt;MaxAgeSeconds&gt;3000&lt;/MaxAgeSeconds&gt;
  &lt;ExposeHeader&gt;Accept-Ranges&lt;/ExposeHeader&gt;
  &lt;ExposeHeader&gt;Content-Range&lt;/ExposeHeader&gt;
  &lt;ExposeHeader&gt;Content-Encoding&lt;/ExposeHeader&gt;
  &lt;ExposeHeader&gt;Content-Length&lt;/ExposeHeader&gt;
  &lt;ExposeHeader&gt;Access-Control-Expose-Headers&lt;/ExposeHeader&gt;
  &lt;AllowedHeader&gt;*&lt;/AllowedHeader&gt;
  &lt;/CORSRule&gt;
  &lt;/CORSConfiguration&gt;
