No connection could be made because the target machine actively refused it

Description of Issue

I am trying trying to establish communication b/w Volttron Agent and a Client running on windows Machine. Both Machines are currently in same Local Network.

My ultimate goal is to run a Simulation (similar to energy Plus) in Windows Environment and connect it to Voltton bus using a Volttron Agent named Apache. The communication b/w the two will be done using Sockets(Client-Server).

I am not able to connect to the server running on Volttron agent (RPi) with the python program in another Machine and getting an error - "[WinError 10061] No connection could be made because the target machine actively refused it"

Steps to Reproduce

More Info- Ip addr of RPi (Server) is '192.168.0.17'

In Server (Apache_integration.py) I mentioned
self.host = '192.168.0.17' self.port = 5005 self.sock.bind((self.host, self.port))

Server Execution is struck indefinitely at recv() Method .

Additional Details
