Error connecting to websocket (socket.io), how to connect?

Question

Node.js

Hello, I wrote a small service on a node using sockets, when I wrote for the test I used postman and everything works fine,
But when I started connecting from in the browser, I started getting an error

websocket.js:89 WebSocket connection to 'wss://myurl.com:3000/socket.io/?EIO=4&transport=websocket&sid=KnZ01Z8nT9vnHCpyAANf' failed:

no error details.
I tried all combinations of connection parameters that I found, in the spirit of:

{
      secure: true,
      rejectUnauthorized: false
 }

 {
      secure: true,
      transports: ['websocket'],
      withCredentials: true,
      rejectUnauthorized: false
 }

but it did not help.

The server with sockets is on a different domain, but I registered the corses,

require('socket.io')(server, {
            cors: {
                origin: '*',
                methods: ["GET", "POST"]
            }

Plus, I added a log to the connection event,

io.sockets
            .on('connection', (socket) => {
                try {
                    console.log('connection');

and when I try to connect from postman - everything is in order, I see it, but the browser does not call anything.
