Invalid frame header

[generalsvr]

I executed npm install && node server.js. When opening new room this error throws:

websocket.js:54 WebSocket connection to 'ws://192.168.1.184:3000/socket.io/?EIO=4&transport=websocket' failed: Invalid frame header

I tried changing socket-io versions, node versions and other stuff

This error we can ignore.
But for me, video call was not working because of this
const myPeer = new Peer(undefined, {
path: "/peerjs",
host: "/",
port: "3000",
});

After comment this port it worked for me :)
