title: Error Loading Stream: Could not connect to server for RTMP stream
body: <p>I have a browser based application which displays an RTMP stream.
  The RTMP stream url is similar to<code>rtmp://xxx.xxx.xxx.xxx:1935/oflaDemo/livestream.flv</code></p>
  
  <p>I can view the live stream from my home network. But from my office, I am unable to view the stream. I am getting the following error: <code>Error Loading Stream: Could not connect to server</code>. </p>

  <p>My office has a firewall running having only few specific ports open like 80, 443, 8443 etc. </p>
  
  <p>My questions are</p>
  
  <p>1) Is this a firewall issue ?</p>
  
  <p>2) If yes, what ports should I ask them to open ?</p>
  
  <p>3) How could I be sure that this is a port blocking issue ? </p>
