ExpressJS: localhost didn’t send any data

I am writing an app, when I start the server, its working nicely, its connecting to database. But when I start http://localhost:5000 from the browser, it does not respond for a minuite then the browser shows a message: 

localhost didn’t send any data.
ERR_EMPTY_RESPONSE

Here is my app.js:

const express = require('express');
const app = express();
const cookieParser = require('cookie-parser');
const mongoose = require('mongoose');
app.use(cookieParser);
app.use(express.json());



//const userRouter = require('./routes/user');
//app.use('/user', userRouter);

const startApp = async () => {
    try {
        await mongoose.connect('mongodb+srv://username:[email protected]/test?retryWrites=true&w=majority',
        { useUnifiedTopology: true,useNewUrlParser: true });
        console.log(`successfully connected to database`);
        const port = process.env.PORT || 5000
        app.listen(port, () => {
            console.log(`server runnin at ${port}`);
        });
    } catch (error) {
        console.log(error.message)
    }
}

startApp();

app.get('/', (req, res) => {
    console.log("I am in the root");
    res.send("hello World");
})

Why server is not responding from the browser?

try 

app.use(cookieParser())

instead of 

app.use(cookieParser)

I had the same problem db is connected but not able to send data. it looks weird but it works for me.

Add a new database user with new password, use the new userName and passw to connect your mongoodb this is the exact like to add new database user

here is my db connection may it helps you too 

mongoose.connect(DATABASE_URL, { useNewUrlParser: true,useUnifiedTopology: true  })
const db = mongoose.connection
db.on('error', (error) => console.error(error))
db.once('open', () => console.log('connected to database'))

app.use(express.json())
