const express = require("express");
const app = express();
const PORT = 8443;
app.listen(PORT, () => {
     console.log("Server up and running")
});

you had some errors first of all you did not initialized the PORT and second you passed PORT as string in app.listen()

You are missing a view normal JavaScript things. Like defining port. And the .listen function takes in the port variable rather than a string saying "PORT" See working example:

const express = require('express');
const app = express();
const port = 8443;

app.listen(port, () => console.log(`Server running on port ${port}!`));

You should use the variable and not the string in the app.listen() function. Try to use something like this:

app.listen(PORT, () => {
    console.log("Server up and running")
});

@Abhishek, I think on which port are you using that is block by your environment kindly allow it on the firewall or just disable the firewall and access again it works for you!!
