Cordova android http not working

Hi, I know that question came up many times, but I’ve now seached the web about two days and tested so many cases, that I think it is time to call some help.

My Case:
I’ve an ionic 2 application with a external API written in node and authenticated with Auth0 and JWT. The main problem is that the request through Http is not calling the API. It is like the app can not call outside itself.

How I produce the error:
Before all I installed the whitelist plugin from cordova and allowed EVERYTHING (here the config.xml: I have also added the http-equiv to my index.html ( Now I’ve stared the app with cordova ionic cordova run android -lcs. My device below.

The error I can archive from my http wrapper (import { AuthHttp } from 'angular2-jwt';) is that:

[14:47:36]  console.log: http://localhost:8080/api/v1/auth/login
[14:47:36]  console.log: {"_body":{"isTrusted":true},"status":0,"ok":false,"statusText":"","headers":{},"type":3,"url":null}

My Service function:

Not yet… but if you find out how I appreciate your answer.

instead of “localhost” use your system ip address

Note: your system and phone should connect to same wifi
