Citrix demands all your servers and test tools are within Citrix.
So yes, SOAP UI will not work from your local desktop.
You either need to use the SOAP UI on a Remote Desktop in Citrix or you need to use WSNavigator.
Go to http://pihost:port/wsnavigator and from there,
- Select WSDL
- Provider your WSDL URL from SOAP Sender Channel
- Provide your credentials and data and test the same.
