可能是由于LORIOT服务器的同源策略和WebSocket的跨域请求问题导致的。开发者可以尝试使用CORS进行解决。

代码示例：

1. 对于Node.js的应用：

const WebSocket = require('ws');
const { origin } = require('./config');

const server = new WebSocket.Server({ port: 8080, origin });

server.on('connection', function (ws) {
  ws.on('message', function (message) {
    console.log('Received: %s', message);
    ws.send(`echo ${message}`);
  });

  ws.on('close', function (code, reason) {
    console.log('Close code: %s, reason: %s', code, reason);
  });

  ws.send('Connected to WebSocket server');
});

2. 对于浏览器的JavaScript应用：

const socket = new WebSocket(`ws://${HOST}:${PORT}`);

socket.onmessage = (event) => {
  console.log(`Message: ${event.data}`);
};

socket.onclose = () => {
  console.log('WebSocket closed');
};

socket.onerror = (error) => {
  console.log(`WebSocket error: ${error}`);
};

socket.onopen = () => {
  console.log('WebSocket opened');
};

请注意，还需在LORIOT的WebSocket服务器端进行配置。具体可以参考LORIOT官方文档。
