I have to come up with a solution for secure streaming for the company I'm working for. I decided to choose Wowza 3.5.2 as the media server and FlowPlayer to access the videos. The Wowza Media Server is running on an Ubuntu 12.04 server. I followed the tutorial to set up Video On Demand. Everything works so far. I can access the videos with the FlowPlayer that are stored in the content folder.
Now, I tried to use RTMPE with a secure token. Again I followed the tutorial to set up the module und properties. My Application.xml now looks like this:

<Root>
	<Application>

The code from the FlowPlayer is as follows (I edited the Minimal Flowplayer setup that comes with the FlowPlayer tutorial):

<h1>Minimal Flowplayer setup</h1>
	
		<p>View commented source code to get familiar with Flowplayer installation.</p>
		
		<!-- this A tag is where your Flowplayer will be placed. it can be anywhere -->
		<a  
			 href="landscapes.mp4" class="player"
			 style="display:block;width:520px;height:330px"  
			 id="wowza"> 
		</a> 
	
		<!-- this will install flowplayer inside previous A- tag. -->
		<script type="text/javascript">
	flowplayer("wowza", "flowplayer-3.2.16.swf",
		{
			clip: {
				provider: 'rtmp',
				connectionProvider: 'secure'
			},
			plugins: {
				rtmp: {
				url: 'flowplayer.rtmp-3.2.12.swf',
				netConnectionUrl: 'rtmp://192.168.3.83:1935/vod'
				},
			secure: {
				url: 'flowplayer.securestreaming-3.2.8.swf',
				token: 'testpw'
			}
			}
		}
	);
</script>
When I now open the FlowPlayer it gives me this error: 201, unable to load stream or clip file, connection failed, clip: [clip]landscapes.mp4
What am I doing wrong?
