const WebSocket = require('ws');
let url = "ws://127.0.0.1:8683/ws";
let ws = new WebSocket(url, {perMessageDeflate: false});
ws.on('open', ()=> { console.log('open'); });
ws.on('message', (msg)=> { console.log('received: '+msg); });
ws.on('error', (error)=> { console.log(error); });
ws.on('close', ()=> { console.log('closed');});

Result:

Error: socket hang up closed

My client websockets implementation in chrome still connects perfectly without problem… this only happens with node sockets.

Closing as the mystery has been solved.
