Im doing my discord activity with vite as discords getting-
started tutorial. I created ws server via Express and Socket.io, in browser it works correctly, but when i launch it in discord it doesn’t work correctly.

client/main.js

import { DiscordSDK } from "@discord/embedded-app-sdk";
import { io } from "socket.io-client";
import "./style.css";

// Will eventually store the authenticated user's access_token
// let auth;
// let VITE_DISCORD_CLIENT_ID = 'DS_APP_CLIENT_ID';
// const discordSdk = new DiscordSDK(VITE_DISCORD_CLIENT_ID);
//
// setupDiscordSdk().then(() => {
//     console.log("Discord SDK is authenticated");
//
//     // We can now make API calls within the scopes we requested in setupDiscordSDK()
//     // Note: the access_token returned is a sensitive secret and should be treated as such
// });

async function setupDiscordSdk() {
    await discordSdk.ready();

    console.log("Discord SDK is ready");
    // Authorize with Discord Client

    const { code } = await discordSdk.commands.authorize({
        client_id: VITE_DISCORD_CLIENT_ID,
        response_type: "code",
        state: "",
        prompt: "none",
        scope: [
            "identify",
            "guilds",
        ],
    });
    // Retrieve an access_token from your activity's server
    const response = await fetch("/api/token", {
        method: "POST",
        headers: {
            "Content-Type": "application/json",
        },
        body: JSON.stringify({
            code,
        }),
    });
    const { access_token } = await response.json();

    // Authenticate with Discord client (using the access_token)
    auth = await discordSdk.commands.authenticate({
        access_token,
    });
    if (auth == null) {
        throw new Error("Authenticate command failed");
    }
    document.querySelector('#app').innerHTML = `
      <div>
        <img src="https://cdn.discordapp.com/avatars/${auth.user.id}/${auth.user.avatar}" class="logo" alt="Discord" />
        <h1>Hello, World! ${auth.user.global_name}</h1>
      </div>
    `;
}
const socket = io('https://ws-server-url.tunneled-by-cloudflared')
socket.on('new_connection', (val) => {
    console.log(`New connection connected ${socket.id}`);
    let p = document.createElement('p');
    p.innerText = val;
    document.querySelector('#app').innerHTML = val;
})

ws-server/server.js

import express from "express";
import dotenv from "dotenv";
import { Server } from "socket.io";
dotenv.config({ path: "../.env" });
const app = express();
const port = 3002;
app.use(express.json());

const server = app.listen(port, () => {
  console.log(`Server listening at http://localhost:${port}`);
});

const wsServer = new Server(server, {
  cors: {
    origin: "*"
  }
});
wsServer.on("connection", (socket) => {
  wsServer.emit('new_connection', socket.id)
  console.log(`New connection connected ${socket.id}`);
})

Can you help me pls?
