WP8 only way to display mvc web service is to include <.fiddler> in url

I am trying to narrow down what is causing my Windows Phone 8 app to fail when trying to connect to my web service from a device. It works perfectly fine in the emulator just not the device, and nothing online seems to have a solution for this scenario. So I am using fiddler to help with tracing what is causing the 'web service not found' exception. On the WP8 device web browser, if I search the following url it is successful, and the host appears in the fiddler debugger:

http://ift.tt/1fQmtLM

If however, I change the url to my original url it fails to find the page and fiddler shows that nothing has happened in the debugger:

http://localhost:54931/test

I'm thinking that understanding what is happening here will help me narrow down the cause of my scenario. Does anyone understand what is happening?
