So I wrote this jar that interacts with a database and also serves as a server. Problem is that I can only interact with that jar when I’m on the lan or run the jar from a different computer. The system with the problem is running windows xp with the firewall disabled and yes it is correctly set up with the router as I can launch a web server and view it remotely. I have no clue what the problem would be as the firewall is disabled and the jar works on other computers on the same network.

Note: I was noticing an exception “java.net.SocketException: Address family not supported by protocol family” earlier
