6 years ago I have a 400 error Bad request
So the remote server doesn't like what you asked for. There's nothing saying it's an lws problem.
ccinfo.port = 443; // port number ccinfo.ssl_connection = 0; // SSL
... you're talking http, not https on 443?
I can not use the websocket with the libwebsocket, I will want to connect to this websocket bitfinex wss: //api.bitfinex.com/ws, and I have a 400 error Bad request, I do not understand how initializes properly lws_client_connect_info, i'd like with an example that works with bitfinex
