The connection refused you get means that your app was not able to establish a socket connection to its target. Typically this means that you've given the wrong hostname or port, or that the service on the other end isn't running.
I suggest that you look into the logs, error messages and/or configuration to find out what address is being used and why a connection can't be established to that address.
Using Telnet to try and establish connections yourself may be very helpful in preliminary investigation.
Telnet <ip/url> <port number>

In addition to what othos suggested as possible causes, this could also be the result of a firewall interfering with the network connection on those ports between your Pega server and the soap UI client.
