Solved
Something to do with 5.5 version. Noticed same with PRO version.
Disabled Proxy service and it works fine on both.
Sorry to come back on this issue. I encounter the same problem, i both deactivated the SOAUPUI proxy and the proxy settings on my Windows10. Still continue to have the problem in SOAPUI 5.4.0 and 5.5.0 What am I missing? Thanks
