Https API Calls dont work only on iOS Ionic 3

Hello, I have the problem that my API Calls works on Android and in Browser but somehow they dont work on iOS Apps? And yes im using https.

Im using import { Http } from '@angular/http'; for my Calls.

Anyone did faced the same issue?



import { IonicErrorHandler } from 'ionic-angular';

import { ENV } from '@env';

import * as Raven from 'raven-js';

const ravenConfig =  {
  release: ENV.version

Raven.config(ENV.sentryDsn, ravenConfig).install();

export class SentryErrorHandler extends IonicErrorHandler {

  constructor() {

  handleError(error: any): void {

    if (!ENV.production) {
      return super.handleError(error);

    try {
      Raven.captureException(error.originalError || error);
    } catch (err) {}
