Laravel broadcasting : laravel-echo-server / redis stop handling event irregularly after 3-4 hours or once in a day

Question

I've implemented broadcasting functionality using driver redis and laravel-echo-server.

Everything is working fine events are working fine too, but the problem is, after some span of time, 3 hours or 6 hours (time is not fixed) , it disconnects automatically even laravel-echo-server is running in the background.

But if I refresh the page everything starts working fine again. I've tries many ways but I could not figure out what is the problem.

My project will run on localhost forever.

File .env

BROADCAST_DRIVER=redis
CACHE_DRIVER=file
FILESYSTEM_DISK=local
QUEUE_CONNECTION=sync
REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379
LARAVEL_ECHO_PORT=6001

laravel-echo-setup.js

import Echo from 'laravel-echo';
