Hi Muhammad, not a great programmer here, but seems that the target machine is the problem. IMO two possibilities, I see you are on a WIndows machine:
- firewall issues ( on the target AND/OR on the source machine) - wrong settings in the sockets ( port mismatch ?) In my experience the XMLRPC scenario it's simple and well documented, but not so 'responsive'. Switching to ZMQ socket ( in this specific case the PUSH/PULL pair seems adeguate) I found that everything works much better. My 1 eurocent :-) Vittorio fingerprint: fb5f492a54e016c632c933d3ee4b7e38203c79ca Inviato con l'email sicura [Proton Mail](https://proton.me/mail/home). lunedì 13 gennaio 2025 11:27, Muhammad Anas <anasg8...@gmail.com> ha scritto: > Dear GNU Radio Community, > > How to resolve this issue? > Traceback (most recent call last): > File "D:\GRC\Lib\site-packages\gnuradio\qtgui\range.py", line 198, in changed > self.notifyChanged(self.rangeType(val)) > File "D:\GRC\Lib\site-packages\gnuradio\qtgui\range.py", line 302, in > sliderChanged > self.notifyChanged(self.rangeType(value)) > File "D:\OneDrive - GNU\Desktop\siggen_controller_xmlrcp_client.py", line 96, > in set_freq > self.xmlrpc_client_0.set_rmt_freq(self.freq) > File "D:\GRC\Lib\xmlrpc\client.py", line 1122, in _call_ > return self._send(self._name, args) > ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > File "D:\GRC\Lib\xmlrpc\client.py", line 1464, in __request > response = self.__transport.request( > ^^^^^^^^^^^^^^^^^^^^^^^^^ > File "D:\GRC\Lib\xmlrpc\client.py", line 1166, in request > return self.single_request(host, handler, request_body, verbose) > ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > File "D:\GRC\Lib\xmlrpc\client.py", line 1178, in single_request > http_conn = self.send_request(host, handler, request_body, verbose) > ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > File "D:\GRC\Lib\xmlrpc\client.py", line 1291, in send_request > self.send_content(connection, request_body) > File "D:\GRC\Lib\xmlrpc\client.py", line 1321, in send_content > connection.endheaders(request_body) > File "D:\GRC\Lib\http\client.py", line 1298, in endheaders > self._send_output(message_body, encode_chunked=encode_chunked) > File "D:\GRC\Lib\http\client.py", line 1058, in _send_output > self.send(msg) > File "D:\GRC\Lib\http\client.py", line 996, in send > self.connect() > File "D:\GRC\Lib\http\client.py", line 962, in connect > self.sock = self._create_connection( > ^^^^^^^^^^^^^^^^^^^^^^^^ > File "D:\GRC\Lib\socket.py", line 851, in create_connection > raise exceptions[0] > File "D:\GRC\Lib\socket.py", line 836, in create_connection > sock.connect(sa) > ConnectionRefusedError: [WinError 10061] No connection could be made because > the target machine actively refused it > >>>> Done (return code 3221226505) > > Regards > Muhammad Anas
