Socket s = new Socket(Some InetAddress Object, Some Port);
Do you have a firewall in the way?
Or a NAT router? Or a proxy? Or something that performs two or more of those functions?
As Knute's reply suggests, if you're having trouble connecting in situations other than being on the same local computer or LAN, the most common reason is that your network is not correct configured to allow the connections to go through.
Writing network code involves a lot more than just using the Socket class. If you expect to be successful, you'll need to take some time to learn about how networking itself works, as well as the specific protocols you plan on using.
