axios.post is returning error when used with redux-saga - react-native

Question

I recently converted my redux-thunk middleware code to use redux-saga and it was working all these days fine and all of a sudden it is throwing an error. Not sure why!!
My Spring Boot REST Client is returning the proper response and no errors in the log. And if i make the same request using swagger i am getting the response back as expected so there is nothing wrong on the server side.
I have the following code
const LOGIN_URL = 'http://localhost:8888/api/a/login';
export function* loginUserAsync(action) {
console.log('.loginUserAsync() : action:', action);
yield put({ type: LoginConstants.LOGIN_USER_IN_PROGRESS });
const postParams = {
username: action.props.username,
password: action.props.password
};
const headerParams = {
headers: {
'Content-Type': 'application/json',
//'Content-Type': 'x-www-form-urlencoded'
}
};
console.log('headerParams', headerParams);
console.log('postParams', postParams);
try {
console.log('Before making async post call using axios');
const response = yield call(axios.post, LOGIN_URL, postParams, headerParams);
let token;
console.log('response', response);
if (response.headers) {
token = response.headers['x-auth-token'];
AsyncStorage.setItem('jwt', token);
}
// Login Succeeded fire Login Success Action
yield put({
type: LoginConstants.LOGIN_USER_SUCCESS,
token,
account: response.data
});
const navigatorUID = Store.getState().navigation.currentNavigatorUID;
Store.dispatch(NavigationActions.push(navigatorUID, Router.getRoute('home')));
} catch (error) {
// Login Failed fire Login Failure Action
console.log('loginUserAync() : error:[' + JSON.stringify(error) + ']');
yield put({
type: LoginConstants.LOGIN_USER_FAILURE,
error: error.data
});
}
}
export function* loginUser() {
console.log('.loginUser() :');
yield takeEvery(LoginConstants.LOGIN_USER, loginUserAsync);
}
In the console i am seeing the following:
I have no idea why it stopped working all of a sudden.
Thanks

For some reason localhost and 127.0.0.1 are not being recognized and i have to use the actual IP Address.
I had that Issue when i tried to run it in my mac book. It always worked with localhost in Ubuntu.
