Unable to access ICS end point Url in SOAP UI Tool

Content

I have created an "App Driven Orchestration" using ICS.

The end point is a rest service.

The orchestration integration is active  and the third part system is able to access the same and push the data .

But I am unable to access the end point url of the rest service using SOAP UI Tool.

Getting error as "java.lang.Exception: Failed to load url;"

Any suggestion what needs to be changed in the SOAP UI tool to be able to access this end point !

I tried to access the same end point url using a java program.  I am getting the error as "peer not authenticated".
