xhr poll error

[toni-monteagudo]

Hi there,

I'm currently using the following code to set up a server in a node.js app:

this.socketsServer = new socketIoServer(3001, {
  cors: {
    origin: "*",
    methods: ["GET", "POST"],
  },
  pingInterval: 10000,
  pingTimeout: 5000,    
});

In another node application, I'm attempting to establish a connection by setting up the client like this:

this.socket = io("ws://127.0.0.1:3001", {
});

However, I'm unable to establish the connection, and I keep receiving the error xhr poll error. It's puzzling because it works fine through the browser.

If anyone could provide a clue, I would greatly appreciate it. Thank you very much!

By the way, I'm using version 4.7.2.

EDIT: I haved tried also adding transports: ['websocket'], option but with no success
