And the launcher window says: Failed to fetch page: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Does anyone has a solution ?
Thanks a lot

Do I need to add this: -Djavax.net.debug=SSL ?
But where ?

Your server certificates may be invalid, or may be invalid in the eyes of java SSL - it has its own certificate store in some cases, so very new certificates (like modern Let's Encrypt) can be regarded as invalid. Check your Java installs and make sure they're all up to date.
