无法使用ipad mini在角度应用程序中获取数据

I am making an angular application for Dashboard. I am making several http requests from my controllers. When i build this project using grunt, it runs well on my machine and fetches the data from the express server which is also running on localhost on port 1222. But when i run the built code on ipad, the app is unable to fetch data. I am totally lost about what could be the possible reason for this.I am making an angular application for Dashboar
