How to prevent libwebsockets client timeout

Question

I am trying to create a C ++ website client using libwebsockets, but I cannot establish a connection due to turning it off. I removed everything for testing, and here is what I use to establish the connection:

Protocols

static int defaultCallback(
    struct  libwebsocket_context* context,
    struct  libwebsocket* wsi,
    enum    libwebsocket_callback_reasons reason,
    void*   user,
    void*   in,
    size_t  len)
{
    return 0;
}

static struct libwebsocket_protocols protocols[] =  {
    { "default", defaultCallback, 0 },
    { NULL, NULL, 0 }
};

Create context

    struct lws_context_creation_info info;
    memset(&info, 0, sizeof(info));
    info.port = CONTEXT_PORT_NO_LISTEN;
#ifndef LWS_NO_EXTENSIONS
    info.extensions = libwebsocket_get_internal_extensions();
#endif
    info.gid = -1;
    info.uid = -1;
    info.protocols = protocols;

    _context = libwebsocket_create_context(&info);

Create client

NOTE . The address is "ws: // localhost". I also tried "ws: //echo.websocket.org". The localhost server is a Node and ws application that I tested in Chrome and works great.

_websocket = libwebsocket_client_connect(_context, // context
                                         _address.c_str(), // address
                                         _port, // port
                                         0, // use ssl?
                                         "/", // path
                                         _address.c_str(), // host
                                         NULL, // origin
                                         NULL,  // protocol
                                         -1);   // version

Service Context

while(1) {
    libwebsocket_service(_context, 50);
}

Exit When I run above, this is the result that I get through the libwebsockets registration callback:
