Are you behind a router?

[Joacim Andersson]

Maybe there's a firewall that blocks the connection attempt?

Are you behind a router?

yes i have a router

[kfcSmitty]

you're trying to connect to a local computer using the external IP address?

Don't do that, as all the computers on the network will have the same address.

Use the address your router assigns them

also, to forward an incoming signal from the router, assign certain ports to certain PC's. That way, any incoming data on those ports will only go where expected

I had a problem of not being able to establish a connection as the server behind a router. If you use the winsock.localip property, it will tell you your ip as per the router, something like 192.168.0.x. You can get your real IP from something like www.whatismyip.com. The client needs to connect to the real ip, but the router needs to know which computer to forward the connection to. Type 192.168.0.1 into your web browser. If you're prompted for a username and password use "admin" and "password". This should bring you to your router, where you can set port forwarding. Then just add a new service with the port you're using to connect with and your localip. If that doesn't work, you've got a different problem or your router has a different way of going about it. Check the manual.
