how to connect socket.io server using socket.io client cpp

I'm trying to connect to the socket.io server that is using parser. The following code connects well to server.

export const connect_push_socket = createAction(CONNECT_SOCKET, () => {
    const socket = io.connect(process.env.NEXT_PUBLIC_WEBSOCKET_URL, {
        reconnection: false,
        withCredentials: true,
        parser: socketIoMsgpackParser
    });

    return {
        socket: socket
    }
});

But when I try to implement that in C++, the connection is immediately lost.

sio::client h;
connection_listener l(h);

h.set_open_listener(std::bind(&connection_listener::on_connected, &l));
h.set_close_listener(std::bind(&connection_listener::on_close, &l,std::placeholders::_1));
h.set_fail_listener(std::bind(&connection_listener::on_fail, &l));

h.connect("wss://gateway.abc.com");
_lock.lock();
if (!connect_finish)
{
cout << "wait\n";
    _cond.wait(_lock);
}

_lock.unlock();
current_socket = h.socket();
h.sync_close();
h.clear_con_listeners();

error code :
