Hello,
I'm using Windows OS for both client and server.
I followed this tutorial,
https://www.youtube.com/watch?v=hKfHwQgAsUo
I configured and executed the server connection, got connected successfully but when the try to connect client with server I get the following error
"TCP: connect to[AF_INET]xxx. xxx. xxx. xxx. xxx: 4001 failed: Unknown error".
Below are the server and client configuration files

I have been working on this from past one week so I request the support team to consider this as priority and provide the solution for the above issue.
Thank you.
