when i use socke.io at normal internet speed it works fine.But when I simulate a slow 3G in the chrome developer console.

This error is displayed:

failed: WebSocket is closed before the connection is established.

How do I configure socket.io for slow internet connection?

This is my configuration:

   io("ws:xxxxx.xxxx", {
        transports: ["websocket"],
        upgrade: true,
        path: "messenger",
        query: {
          token: "xxxxxxxxxx",
        },
        timeout: 1000,
    });

note: this configuration works on a fast connection.
