Connection closed before receiving a handshake response

I am prototyping a websocket server using Alchemy. Server runs fine but when trying to open a connection from a browser, it cannot established a connection and the error is

WebSocket connection to 'ws://localhost:81/' failed: Connection closed before receiving a handshake response

you can't use localhost, try to use your real IP adress. like 192.168.1.5 or somthing like that
