I am trying to send instructions from a Django website to a robot(Raspberry Pi) using Sockets but whenever I try and send a second instruction from the website it gives me the error. If you have any idea what is causing this, the help would be amazing! Website Send View:

def form_valid(self, form, **kwargs):
        robo_pk = self.kwargs['pk']
        robo = Robot.objects.get(pk=robo_pk)
        PORT = robo.port
        SERVER = robo.server
        ADDR = (SERVER, PORT)
        self.object = form.save()
        client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        client.connect(ADDR)

        def send(msg):
            message = msg.encode(FORMAT)
            msg_length = len(message)
            send_length = str(msg_length).encode(FORMAT)
            send_length += b' ' * (HEADER - len(send_length))
            client.send(send_length)
            client.send(message)

        send(form.cleaned_data['path_options'])
        send("MESSAGE SENT :) !")
        send(DISCONNECT_MESSAGE)
        return render(self.request, "dashboard-home/thank-you.html")
