Current behavior

When using ssl on the dev server configuration and the Nestjs instance the request won't reach the server.

// main.ts
const httpsOptions = {
  key: fs.readFileSync(process.cwd() + '/storefront_app/config/server.key'),
  cert: fs.readFileSync(process.cwd() + '/storefront_app/config/server.crt')
};

async function bootstrap() {
  console.log(process.cwd() + '/storefront_app/config/server.crt');
  const app = await NestFactory.create(AppServerModule, {
    httpsOptions
  });
await app.listen(process.env.PORT || 4000);
...
}

// angular.json
...
"serve-ssr": {
          "builder": "@nguniversal/builders:ssr-dev-server",
          "options": {
            "ssl": true,
            "sslCert": "storefront_app/config/server.crt",
            "sslKey": "storefront_app/config/server.key",
            "browserTarget": "ui:build",
            "serverTarget": "server:build",
            "port": 4200,
            "host": "0.0.0.0"
          },

Expected behavior

The request should reach the server as it does wihtput using the httpOptions in the NestFactory.
When requesting a page using https and bootstrapping the Nest app instance without the httpOptions the request will reach the server as expected.

Minimal reproduction of the problem with instructions

We're following the instructions provided in this sample repository.
https://github.com/TrilonIO/universal-nest
When the app is configured as stated above the issue will occur.

What is the motivation / use case for changing the behavior?

We need the httpOptions to be able to use the push method on the response object.
