Hi I am having an issue that when on VPN I get the below failures but off of VPN it works fine. I was told our VPN is only monitoring not blocking. Is there any blacklisting going on of IPs?

That you would have to ask JCenter. But "PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target" usually means, that you either have some man-in-the-middle that gives wrong HTTPS certificates, or a broken Java runtime where some root certificates are missing or algorithms are disabled or not present. You could enable

javax.net.debug

logging to get in-depth details about the HTTPS communication and why it failed.
