            {"headers":{"normalizedNames":{},"lazyUpdate":null,"headers":{}},"status":0,"statusText":"Unknown
            Error","url":null,"ok":false,"name":"HttpErrorResponse","message":"Http failure response for (unknown url):
           0 Unknown Error","error":{"isTrusted":true}}

Note: Other apps usually connect to the same emulator
Note: Postman normally connects, Node Js (request) normally connects

Code:

import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Injectable } from '@angular/core';

@Injectable()
export class AuthService {

    constructor(
        private http: HttpClient) {
    }

    loginTest() {

        this.http.get('https://www.google.com/')
            .subscribe(
                ret => {
                    console.log('ret: ', JSON.stringify(ret));
                    alert('ret: ' + JSON.stringify(ret));
                },
                error => {
                    console.log('error: ', JSON.stringify(error));
                    alert('error: ' + JSON.stringify(error));
                }
            );
    }
}
