I am receiving an Error: xhr poll error in the connect_error event when trying to connect to my websocket gateway.
I am using "socket.io-client": "^4.2.0".

import { io } from "socket.io-client";



const ENDPOINT = "http://localhost:3001";



const socket = io(ENDPOINT);



socket.on("connect_error", (e: any) => {

   console.log(e);

});

You can try to set up the client connection to use only websocket transport. By default it is using weboscket and polling.

{

   transports: ['websocket']

}

So your code will become:

const socket = io(ENDPOINT, {

   transports: ['websocket']

});
