Connect to a Kepware KepServerEx V6 that runs on Windows using python in Ubuntu

Question

I'm new to this Kepware KEPServerEX V6 thing that I run in Windows 11 locally. Now, I am creating a client via python-opcua package from https://github.com/FreeOpcUa to connect to it but had a connection refused issue. Can anyone help me. And what are the things I need to setup in-order to establish a successful connection from my client to the KEPServerEX.

Here's a litte snippet:

import sys
sys.path.insert(0, "..")
from opcua import Client

if __name__ == "__main__":
    client = Client("opc.tcp://127.0.0.1:49320")

    try:
        client.connect()
    except Exception as e:
        print(e)

Here the error result: [Errno 111] Connection refused

I tried searching on google and youtube.com but I couldn't find any resources that is related to my issue.
