Node.js login app works on http but not https (using IIS reverse proxy)

I am trying to get my IIS hosted website to allow me to login to Auth0 application and proceed back. My issue is it all works fine on http. Then I make the correct Node.js adjustments to turn my app https. But then my issues are the following:

This is my IIS web.config settings:

<system.webServer>









</system.webServer>

I will attach my server.js and index.js (route) files for reviewing. I will also attach my application settings from auth0:

Here is server.js

const dotenv = require('dotenv');
const express = require('express');
const https = require('https');
const logger = require('morgan');
const path = require('path');
const router = require('./routes/index');
const fs = require('fs');

const { auth } = require('express-openid-connect');

dotenv.config();

const app = express();

app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');

app.use(logger('dev'));
app.use(express.static(path.join(__dirname, 'public')));
app.use(express.json());

const config = {
  authRequired: false,
  auth0Logout: true,
  secret: '',
  baseURL: 'https://testing.dupps.com',
  clientID: 'oPqqTSH4b6k3FlZGZqdItV2KBVPVR3w8',
  issuerBaseURL: 'https://dev-wg2ioezy8v4cunjl.us.auth0.com'
};



const port = process.env.PORT || 3067;
if (!config.baseURL && !process.env.BASE_URL && process.env.PORT && process.env.NODE_ENV !== 'production') {
  config.baseURL = `https://testing.dupps.com`;
}

app.use(auth(config));

// Middleware to make the `user` object available for all views
app.use(function (req, res, next) {
  res.locals.user = req.oidc.user;
  next();
});

app.use('/', router);

// Catch 404 and forward to error handler
app.use(function (req, res, next) {
  const err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// Error handlers
app.use(function (err, req, res, next) {
  res.status(err.status || 500);
  res.render('error', {
    message: err.message,
    error: process.env.NODE_ENV !== 'production' ? err : {}
  });
});

// Path to your PFX file and passphrase if needed
const pfxPath = path.join(__dirname, 'key.pfx'); // Adjust the path accordingly
const passphrase = '1234'; // Change this to your actual passphrase

// Create HTTPS options with PFX certificate
const httpsOptions = {
  pfx: fs.readFileSync(pfxPath),
  passphrase: passphrase // If there's no passphrase, you can omit this
};

// Start the HTTPS server
https.createServer(httpsOptions, app)
  .listen(port, () => {
    console.log(`Listening securely on ${config.baseURL}`);
  });

and here is index.js (route):

var router = require('express').Router();
const { requiresAuth } = require('express-openid-connect');

router.get('/', function (req, res, next) {
  res.render('index', {
    title: 'Auth0 Webapp sample Nodejs',
    isAuthenticated: req.oidc.isAuthenticated()
  });
});

router.get('/profile', requiresAuth(), function (req, res, next) {
  res.render('profile', {
    userProfile: JSON.stringify(req.oidc.user, null, 2),
    title: 'Profile page'
  });
});

module.exports = router;
