Deselect Enable SSL Cert Checking.
If it works then there could be a problem with the Cert, or the probe's ability to check it.
Note: If you are using Self Signed Certificates then import the certificate from the Java Trust Store.
As per the release notes when SSL is enabled:
In the probe Raw Configuration interface > startup section, add -Dhttps.protocols= TLSv1.2,TLSv1.1,TLSv1,SSLv3 to the options key value.
