How to implement guide with websocket connection resetting in node.js with socket.io after 60 seconds
I've hit a wall trying to I've tried everything I can think of but I'm experiencing an scenario with my Node.js application using Socket.io where WebSocket connections are getting reset after approximately 60 seconds of inactivity. I've set up a basic server and client using Socket.io version 4.0.0, and I am using an Express server. The clients can connect successfully and send messages initially, but after they remain idle for about a minute, the connection drops, and I receive this behavior in the console: `WebSocket connection to 'ws://localhost:3000/socket.io/?EIO=4&transport=websocket&sid=...' failed: behavior during WebSocket handshake: Unexpected response code: 404`. I’ve tried adjusting the `pingTimeout` and `pingInterval` options in my Socket.io server settings, but it doesn’t seem to help. Here’s the relevant code I’m using: Server-side code: ```javascript const express = require('express'); const http = require('http'); const { Server } = require('socket.io'); const app = express(); const server = http.createServer(app); const io = new Server(server, { pingTimeout: 30000, // Increase timeout to 30 seconds pingInterval: 10000 // Ping every 10 seconds }); io.on('connection', (socket) => { console.log('a user connected'); socket.on('disconnect', () => { console.log('user disconnected'); }); }); server.listen(3000, () => { console.log('listening on *:3000'); }); ``` Client-side code: ```javascript const socket = io('http://localhost:3000'); socket.on('connect', () => { console.log('connected to server'); }); socket.on('disconnect', () => { console.log('disconnected from server'); }); ``` I've also confirmed that there is no reverse proxy in front of my application that might be causing this scenario. Additionally, I've checked for any firewall settings that could be interrupting the WebSocket connection. Can anyone guide to identify what might be causing this connection reset and how to resolve it? Thank you! This is part of a larger REST API I'm building. Is there a simpler solution I'm overlooking? Any examples would be super helpful.
