My websocket has two connections, one with ?sid params keeps failing, retry won't work either, but sometimes it works

Question

My App uses socket.io package + laravel-echo package, and when it connects, it makes two requests like this screenshot.

One request without sid parameter is fine, and my app can work normally.

However, the one with sid parameter request keeps failing, I don't know why.

And that request will retry, and still failing like this.

Sometimes the request with sid param will work, and no matter its success or failure, my app will work normally.

Why is this happening?
