SocketException: Permission denied: connect

I was wondering in what other circumstances this (SocketException: Permission denied: connect) error would be thrown from the line ``` SocketAddress socketAddress = new InetSocketAddress("86.143.5.165", 6464); // Set a 3s timeout clientSocket.connect(socketAddress, 3000); ``` There are a few Android issues relating to permissions, and when using a port < 1024. I am running a simple java client/server app, on port 6464, and i am using java 1.6.0_32 (after reading that Java 1.7.0_7 adds ipv6 support). I have port 80 forwarded to my server (verified on the client machine by going to my external IP in a browser), and the port 6464 is open also. Why would the client be refused connection? EDIT: I did originally get this error when trying to connect to the server from the server itself. (Obviously, I guess it's like a telephone in that you get an engaged tone). I had a friend test it, and he could connect. I'm now connecting from a laptop that isn't on the LAN (i.e. using a 3g mobile as a hotspot), but strangely still getting the error.
