How to close websocket-connection manually in Cowboy-server?

Question

How can I close a websocket connection manually (from server side) in Cowboy-server? I would check login/password in callback-module in init/3 and kick "wrong" users with some return code. What is the best way to do this?

Try to return {shutdown, Req, State} from your handler:
