Answer 1

const mongoose = require('mongoose');
const option = {
    socketTimeoutMS: 30000,
    keepAlive: true,
    reconnectTries: 30000
};

const mongoURI = process.env.MONGODB_URI;
mongoose.connect(mongoURI, option).then(function(){
    //connected successfully
}, function(err) {
    //err handle
});

Answer 2

If you are sure that you exported port -p 27017:2017 and it still doesn't work.

Check your VPN if it is not blocking Local Network sharing.

Answer 3

Your query is taking a long time. And mongo itself has a default time out set. So it times out, if the query takes longer than the timeout time.

Answer 4

you have to use this configs on your connection: keepAlive: 300000, connectTimeoutMS: 30000
