Nativescript: HTTP failure response for unknown URL

I have a situation, I have pulled the latest changes from my branch and trying to run the application using tns run android command. The app is launched successfully but the API call is restricted throwing an error as soon as the app starts.

I have also gone through this answer but that's not the problem it seems. Because for other team members it is working fine. :/
