A probable cause for this exception is that the proxy server port has been configured with the wrong port number. Insure that the proxy server port has been entered correctly in the Use SSL proxy Port field. This port number is obtained from the network administrator, or proxy owner. Make necessary changes and retry the test. If the failure continues to occur, contact your next level of support for problem resolution and have them collect the /var/log/messages and the iqyylog.log files.
