I just attempted an upgrade from 3.6 to 4.0 hosted engine and ran into an problem. The hosted engine vm updated without issue, but when I go to login to the web interface to continue the process I get: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at every page load and I can't login. I have a feeling that the issue comes from where I replaced the self-signed certs with trusted ca signed certs a year ago. Is there a work around? CentOS 7.2 Thanks, -- Matt Haught
