re stream cutting out

Hi all,

I am currently running a few ip cams to wowza over a 3g connection and then serving it to my web page through cloudfront. I keep getting the same problem where a stream will stop being sent out from wowza to the client. In the engine manager it is still showing as bytes coming in but none going out, the video is definitely fine because I am recording it and none of the videos are missing chunks.

The strange thing is that when I use the test player on wowza manager it plays fine and then afterwards it starts sending data again. I don’t know why the requests from the page and AWS are not making wowza provide the video but running the test player does. It only has this problem now and then and it does it randomly with each stream

These are the errors I am getting in my Error and Access log when it is happening
