**如果我的解释不好，请写评论！**我遇到了一个奇怪的问题，我有一个socket.io服务器使用NodeJs Express 5.0。我有socket.io客户端，可以使用任何WebBrowser从Windows/MacOS/Linux连接，并且socket.io的连接没有任何问题。

但从Android/iOS应用程序不工作，我没有得到任何错误在nginx，或在nodejs应用程序.我看到的唯一错误是使用usb-debugging和chrome：//inspect/#devices -> tab（networking）。在选项卡中，我看到：这个请求作为STATUS（挂起）持续半秒，之后它就（取消）了

URL: mydomain.com/socket.io/?EIO=4&transport=polling&t=Oc7fPq6 
STATUS: canceled
TYPE: xhr
SIZE: 0 B

已更新！！！！这是Android App的错误日志

服务器（Socket.IO和Express Code）：

let SocketServer = require('./core/socket_server.js');
const bodyparser = require('body-parser');

const cors = require('cors');
const express = require('express');
const app = express();

const server = require('http').createServer(app);

const io = require('socket.io')(server, {
  cors: {
    origin: "*",
    methods: ["GET", "POST"],
    transports: ['websocket', 'xhr-polling'],
    credentials: false
  },
  allowEIO3: true
});

let SockServer = new SocketServer(io);

app.set('view engine', 'ejs');
app.use(bodyparser.json());

app.use('/call/:room_id/:user_id/:video_state', express.static('public'));

app.get('/call/:room_id/:user_id/:video_state', async (request, response) => {

  await response.render('video_chat', {
      room_id: request.params.room_id,
      user_id: request.params.user_id,
      video_state: Number(request.params.video_state)
      });
});

server.listen(5001, "0.0.0.0");
SockServer.ServerInitialize();

app.use(cors({
