Hi, I set up a Laravel WebSocket server, and it works fine, but sometimes I this error especially when I have many connections to the WebSocket server at almost the same time (for example if I refresh the dashboard several times and try to connect to the WebSocket) the issue seems to be happening only in production.

Connection id 479386461.347846647 sending message {"event":"pusher:connection_established","data":"
{\"socket_id\":\"479386461.347846647\",\"activity_timeout\":40}"}

here is what my Nginx config looks like

It was a discussion which I tried to turn into an issue. But basically what's happening is If I make like 5 connections almost simultaneously. The WebSocket server stops responding.
