Socket connection in IE 11

Currently i’m using SocketIo to make chat application. It doesn’t have any problem in Chrome. But in IE 11, after few minute, i can’t use socket to emit event. It seems socket connection is disconnected.

I searched and found any issue about timeout of tcp/socket in IE 11. But still can’t found solution.

I only use websocket for socket.io, prevent them use long-polling. The config socket in client side like below:

import socket from 'socket.io-client';

socket('/test', { transports: ['websocket'], upgrade: false });

Server i’m using express and socket redis

import socketio from 'socket.io';
import socketioRedis from 'socket.io-redis';


const ioRedis = socketioRedis('redis://localhost:6379');
const io = socketio(server, {
  adapter: ioRedis,
  transports: ['websocket'],
});
