title: Amazon S3 Error Firewall Provisional headers are shown
body: <p>I am having a issue regarding Amazon S3 urls giving the error </p>
  
  <blockquote>
    <p>Provisional headers are shown </p>
  </blockquote>
  
  <p>I only seem to get this error when i am connected to the wifi over certain networks my main problem is when i am in starbucks on their WIFI i get the error but on any other WIFI i dont get the error and the video will play fine.</p>
  
  <p>I am using the latest Amazon PHP SDK to provide signed urls like below.</p>
  
  <pre><code>$url = $client-&gt;getObjectUrl('videos', 'movie.mp4', '+59 minutes', array(
                              'ResponseContentType' =&gt; 'video/mp4'
                          ));
  </code></pre>
  
  <p>This will generate me a signed url like this.</p>
  
  <blockquote>
    <p><a href="https://video.s3.amazonaws.com/movie.mp4?response-content-type=video%2Fmp4&amp;AWSAccessKeyId=AKIAJHLH6A2TDNLM37YQ&amp;Expires=1409164722&amp;Signature=melsHcsVaXRONs72dhNqM407Cnc%3D" rel="nofollow">https://video.s3.amazonaws.com/movie.mp4?response-content-type=video%2Fmp4&amp;AWSAccessKeyId=AKIAJHLH6A2TDNLM37YQ&amp;Expires=1409164722&amp;Signature=melsHcsVaXRONs72dhNqM407Cnc%3D</a></p>
  </blockquote>
  
  <p>Below is the working version which has a content range bytes</p>
  
  <pre><code>    Accept-Ranges:bytes
      Content-Length:141956
      Content-Range:bytes 9223221-9365176/9365177
      Content-Type:video/mp4

  <p>But when i am on starbucks WIFI i get the error.</p>
  
  <p>Provisional headers are shown </p>
  
  <p>But no bytes range 0-</p>
  
  <p>I know this is vague question and someone will probably instantly down vote it but it is a genuine issue i am experiencing and i really need to get it resolved.</p>
  
  <p>It means anyone watching videos on my website wont be able to view them over certain WIFI connections normally public ones all i can think is it maybe a firewall error.</p>
  
  <p>Any help please or suggestions </p>
