This means it failed over to that. Test the RTMP connnection and stream name with the Wowza SimpleVideoStreaming player
[install-dir]/examples/SimpleVideoStreaming/client/simplevideostreaming.html
Server: rtmp://xx:1935/live/lq
Stream: mp4:sintel.mp4
You can run Wowza in stand-alone (/bin/startup.bat) mode instead of as a service so you can see log output in the console, which is helpful to debug.
