sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
This is a common SSL error. Are you on a corporate network? I suspect your company is cert pinning – Your local JAVA Keystore does NOT trust the certificate.
You either need to add your companies certificate chain to your JAVA Keystore or you need to work out a proxy that does not get pinned.
