Apache reverse proxy for websocket doesn't working - laravel

Question

I have an issue with my WebSocket setup with Laravel and Apache (cPanel installed apache for me).
I'm using a reverse proxy to proxy requests from MY_DOMAIN/socket.io/ to localhost:6001/socket.io and I'm using mod_proxy_wstunnel too.
It was Ok and was running till yesterday and suddenly, it stopped working! Now I'm getting 301 status and nothing else!
I'll share my ws.conf file, my echo server configuration, and, my client-side code with you right below:
ws.conf
ProxyRequests off
ProxyVia on
RewriteEngine On
RewriteCond %{HTTP:Connection} Upgrade [NC]
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteRule /(.*) ws://localhost:6001/$1 [P,L]
<Location /ws/>
ProxyPass http://localhost:6001/socket.io
ProxyPassReverse http://localhost:6001/socket.io
Order allow,deny
Allow from all

},
"apiOriginAllow": {
"allowCors": false,
"allowOrigin": "",

"allowHeaders": ""
}
}
client-side code:
import Echo from 'laravel-echo';
if(window.Laravel){
window.Echo = new Echo({
broadcaster: 'socket.io',
host: window.Laravel.wsurl, // (I'm setting it in blade)
disableStats: true,
path: '/ws/',
enabledTransports: ['ws'],
transports: ['websocket', 'polling', 'flashsocket'],
csrfToken: window.Laravel.csrfToken
});
}
I have to add, server resources are something like this:
RAM: 64GB (used: 7GB and the rest of it is free)
CPU: AMD5-3600
H.D.D: 240 GB (used: 10GB)
I'll be appreciated any response. :)
