I’m not familiar with what code you are using, but you will need to have
a port open on the server you are trying to connect to. In your case, a
port should be open on port 5000 at 172.20.2.89 in order for your client
code to connect to it. If you enter 127.0.0.1 then you’ll need a server
running on your local computer opening port 5000.

Subject: [Discuss-gnuradio] Connection Refused when transmitting
I am currently trying to transmit a picture using the TCP transmission.
However, there are some problem regarding the transmission side. It
appears that the port is blocked as there is a socket error which states
please input server IP address: 172.20.2.89
please input esrver port (default is 5000): 5000
Traceback (most recent call last):
File “MainFrame.py”, line 180, in OnTransmit
File “”, line 1, in connect
socket.error: (111, ‘Connection refused’)
The result is the same even if i input the IP address as 127.0.0.1.
Help is much appreciated! Thank you so much!
