Bluetooth connection using Winsock c++ - c++

Question

I'm currently working on a project trying to connect two PC's using Bluetooth and Winsock, my idea is to develop a server/client connection between them and send a string from the client to the server but unfortunately, it is not working as I was expecting.
When I run the server code it keeps waiting for the client request and only shows in the console "Listen() is ok! Listening for connection". And when I run the client code it runs the entire code until it shows the message "WSACleanUp() works fine". I paired both computers because I thought it was necessary to do so.
My initial guess is that the client connection to the server is not working. I'm new using Winsock and I'm struggling to find accurate information that could help me to fix these issues (besides some questions previously posted and documentation from windows).
