Express-Openid-connect issues connecting to IssuerURL

Question

I am trying to connect to Oauth provider and I am also pretty new to this.

I have an environment file with the following details

ISSUER_BASE_URL=//issuer URL
CLIENT_ID=//client ID
BASE_URL=http://localhost:3000 //nodejs project base URL
SECRET=<long string>

I also have the following code to get it working

const express = require('express');
const { auth } = require('express-openid-connect');
require('dotenv').config();
const app = express();    

app.use(auth());
app.get('/', (req, res) => {
  res.send(`hello ${req.oidc.user.name}`);
  //res.send("index")
});

app.get('/callback', (req, res) => {
    res.send("logged in");
  });    

app.set('trust proxy', true);
app.listen(3000, () => console.log('listening at http://localhost:3000'))

When I run this I get the following error

 UnhandledPromiseRejectionWarning: AggregateError: Issuer.discover() failed.
    RequestError: certificate has expired

With the same details, I am able to connect to the OAUTH provider using an Oauth playground. Not sure what I am doing wrong. Please help.
