I am using Ionic native http to make server requests. The server is hosted on aws and the apis are up and running (verified by postman).

When i do ionic serve the requests go through and work but when i try to run it on device it doesnt work. On inspection i get "net::ERR_CLEARTEXT_NOT_PERMITTED" and post is sent as OPTIONS

ERROR HttpErrorResponse {headers: HttpHeaders, status: 0, statusText: "Unknown Error", url: "http://18.220.143.133/api/login", ok: false, …}

already tried adding to config.xml

login(user: User): Observable<AuthResponse> {
return this.httpClient.post('http://18.220.143.133/api/login', user, {
  headers: new HttpHeaders().set('Content-Type', 'application/json'),
}).pipe(
  tap(async (res: AuthResponse) => {

    if (res.success == true) {

      await this.storage.set('user',res.user);

       await this.storage.set('ACCESS_TOKEN', res.token);
      this.authSubject.next(true);
    }

  })
);

}

I expect http requests to go through from mobile devices as well.

The same happened to me, until in the config.xml file I added:

<preference name = "android-targetSdkVersion" value = "27" />

It has to do with your CORS for the API call. This may help. Also, since you're using Angular HTTP requests, check here HTTP request from angular will send with method OPTIONS instead of POST.
