hi, the attached error is not sufficient for real root-causing, however the same message is a symptom with one typical configuration error when using the underlying test suite. as a rule, in test configuration props you need to specify SSO addresses in the same form, as used when installing vSphere and SRM to create component registrations in Lookup Service - and the recommended address form is normally FQDN. if testbed was installed with FQDN, but you have used IP addresses in configuration props (or vice versa), you can get this error. so make sure props match the addresses used for LS registration. if this doesn't resolve the issue, please post the complete stack trace for the error, as the headline error message wouldn't be enough to diagnose the problem.
