SSLException when attempting to invoke HTTPS mock service

I am currently using soapUI 4.5.2. and I am in fact using "https" on the endpoint.

Also, I followed step by step the following link:
http://www.soapui.org/Service-Mocking/s ... h-ssl.html

But when I change the endpoint to be: https://localhost:8442/mock

I get the following exception:

Tue Jul 02 08:46:27 EDT 2013:ERROR:org.apache.http.conn.HttpHostConnectException: Connection to https://localhost:8443 refused
org.apache.http.conn.HttpHostConnectException: Connection to https://localhost:8443 refused
at com.eviware.soapui.impl.wsdl.support.http.SoapUIMultiThreadedHttpConnectionManager$SoapUIClientConnectionOperator.openConnection(SoapUIMultiThreadedHttpConnectionManager.java:321)

PS. The mock service is running.
