Ionic proxy not working

Hi Guys,

I’m new with Ionic Framework. I just want to connect my external api and listing the item. When I connect with my external API loaded from local machine it is working. But when I try to connect the api from outside the network it is throwing 500 internal server error.

I checked the external API access in emulator in google browser, it is connecting. Can anyone help me to resolve this issue.
