Http get with Angular / Tizen on device

Question

When I try to do a http GET request but I have a "Failure response for https://httpbin.org/get: 0 Unknown Error.".

No CORS because no problem with POSTMAN ...

I have <tizen:privilege name="http://tizen.org/privilege/internet"/> in my config.xml

Anyone has already done an Angular2 / tizen app with http requests plz ?

I tried to add this httpheaders

  const httpOptions = {
  headers: new HttpHeaders({
    'Content-Type': 'application/json',
    'Access-Control-Allow-Origin': '*',
    'Access-Control-Allow-Credentials': 'true',
  }),
};


this.http
  .get(environment.apiBaseUrl + '/ScreenInfo/getDataTV', 
    httpOptions
  ).subscribe(data => {
    this.dataTv = 'OK ' + data;

  },
err => {
  this.dataTv = 'Err  ' + JSON.stringify(err);
});
