Can't login to JiGLE

[yesthisis]

Running windows 7 and Java 1.8

When I start jigle and attempt to login I get an "Authenication Failed", with this in the command line:

we are self-serving
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

This happened last week, I downloaded a new copy and tried again, same thing. Any suggestions?

Java version:
