Android white screen when running ionic capacitor run with SSL

Question

I'm trying to run a simple test, trying to add ionic and capacitor to an already existing angular project. I have managed to make it work and run correctly but when I add the SSL command to the CLI so that the server runs with HTTPS the app no longer loads and everything I can just see is a blank screen. Moreover if I access the URL manually from the browser everything loads correctly. Could it be there's something wrongly configured in Android Studio or the ionic/capacitor files? I have tried different configurations and different emulated devices w/ different Android versions but there's no use, I haven't been able to make it work. I would certainly appreciate if someone could help me with this...

Capacitor.config

import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  appId: 'io.ionic.starter',
  appName: 'iotest',
  webDir: './android/www',
  bundledWebRuntime: false
};

export default config;
