Ionic IOS app unable to make HTTP call


I have an IONIC app that runs on IOS browser. But unfortunately when ran in an Xcode IOS Emulator, I can’t see any data (probable reason being inability to connect to internet from within the emulator).
Please note that the backend API s are hosted in kubernetes running in another machine.

IOS version is 10.XX, Xcode 9.2

Could you please tell what am missing?
