Minim server 2.2 Activation trouble

[aquad1]

Thank you for this link. I followed every step and it seems all went well. In my configuration page it says Minimserver is running but it still says update 247. When i try to activate license I still get this message.

Unable to connect to license server: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
