My webserver is not listening on port 2000, the Jetty back end server of the app is. The app is a maven build of apache spark which runs the Jetty server; I have it set to listen on port 2000.
The app in "any requests the app makes" would be the frontend of the server that uses jquery for requests. The remote IP as shown from the developers console in Google chrome. I looked at the failed GET request. I know the problem is not caused by the SSL rewrite (tested by turning of SSL module).
