How to detect if net.Socket connection dies - node.js

Background

I am communicating with a machine using net.Socket via TCP/IP.

I am able to establish the connection and to send and receive packets of Buffers, which is all fine.

Problem

The problem is that if I manually disconnect the internet cable from the machine, my Node.js connection doesn't fire the close event and I have no means to know if something failed!

Code

let socket;

const start = async function ( config ) {

    await connecToBarrier( config.barrier )
        .then( () => console.log( "connected to barrrier" ) )
        .catch( err => {
            throw new Error( `Cannot connect to barrier: ${err}` );
        } );
};

const connecToBarrier = function ( connectOpts ) {
    return new Promise( ( resolve, reject ) => {

        socket = net.createConnection( connectOpts, () => {
            //once I receive a 'hello world' from the machine, I can continue
            socket.once( "data", () => resolve() );
        } );

        socket.on( "connection", () => {
            console.log("onConnection says we have someone!");
        } );

        socket.on( "error", err => {
            console.log(`onError says: ${err}`);
            reject(err);
        } );

        socket.on( "timeout", () => {
            console.log("onTimeout says nothing");
            reject();
        } );

        socket.on( "end", () => {
            console.log("onEnd says nothing");
            reject();
        } );

        socket.on( "close", err => {
            console.log(`onClose says: ${err}`);
            reject(err);
        } );
    } );
};


start();
