Error when using Realm in React Native

React Native app works fine on emulator (debug + no debug) as well as Android device (no debug). But when I connect my app with chrome for debugging, it gives below error: Failed to execute 'send' on 'XMLHttpRequest': Failed to load ' http: //192.168.1691.130/create_session '

Real version: react-native-cli: 2.0.1 react-native: 0.42.3
