I am not able to solve the mongodb connection problem. I am getting the error below on starting node app.

Here is my mongoose connection code.

var mongoose = require('mongoose');

mongoose.Promise = global.Promise;
mongoose.connect(process.env.MONGODB_URI || 'mongodb://127.0.0.1:27017/ml').then(
    () => { console.log('Connected to mongodb!') },
    err => { console.log('Failed to connect to mongodb'); console.log(err); }
);

module.exports = {mongoose};

Here is the error.

Started up at port 80
Failed to connect to mongodb

Got solution!

Use sudo before the command to start server.
