im writing my first chat app in nodejs , my app basically keeps track of online users and put them in the rooms to chat via webrtc ...im using pm2 to run the chat server

so i noticed sometimes when i close browser tabs my app will crash and pm2 will reload the server so i checked the log and saw this error

0|chat  | Error: read ECONNRESET
0|chat  |     at TLSWrap.onStreamRead (node:internal/stream_base_commons:220:20) {
0|chat  |   errno: -104,
0|chat  |   code: 'ECONNRESET',
0|chat  |   syscall: 'read'
0|chat  | }

here is the error when runing withouth pm2

node:events:368
      throw er; // Unhandled 'error' event
      ^

Error: read ECONNRESET
    at TLSWrap.onStreamRead (node:internal/stream_base_commons:220:20)
Emitted 'error' event on TLSSocket instance at:
    at emitErrorNT (node:internal/streams/destroy:157:8)
    at emitErrorCloseNT (node:internal/streams/destroy:122:3)
    at processTicksAndRejections (node:internal/process/task_queues:83:21) {
  errno: -104,
  code: 'ECONNRESET',
  syscall: 'read'
}

to make sure it's not my code causing this error i removed all the codes in my app and just put 2 simple function to listen to online(called by online client via socket.io) and disconnect(called automatically by user disconnect ) events ... and sure enough after closing and opening some tabs it happen again here is simplified version of my code

im using Express.io which is a combination of Express and Socket.io

const  env = require('dotenv').config({ path: '.env' })
const https = require('https');
const fs = require('fs');

app = require('express.io')();

var options = {
    key: fs.readFileSync( env.parsed.SSL_KEY),
    cert: fs.readFileSync(env.parsed.SSL_CERT)
};
app.https(options).io();
console.log('|-> protocol : https ');



app.io.route('online' , function (req){
    console.log(`| online socket -> ${req.socket.id}`);
})


app.io.route('disconnect', function(req) {
    console.log(`|->****************** disconnect : ${req.socket.id}`);
});

var PORT = env.parsed.PORT  || 8080
console.log(`|-> listining to port ${PORT} `);
app.listen(PORT );

i've searched online and know why it's happening (i think) but i dont have any data communication in this code it .... i've no idea how to handle this and appreciate any help

here is the complete log you can see it happening after closing some tabs
