I wrote the below code

    def can_connect():
        with closing(socket()) as s:
            s.settimeout(SOCKET_TIMEOUT_FOR_POLLING)
            conn = s.connect_ex((host, port))
            Message.new(message_type='acceptance:verify_socket', host=host, port=port, result=conn).write()
            return (conn == 0)
    dl = loop_until(reactor, can_connect)
    return dl
