When Users are trying to download the Palladian nodes from the below URL’s they are unable to download and facing below mentioned error.
- We requested the user to install the new version of KNIME Client 4.1.4 which didn’t helped to solve the issue.
- As we observed the Exceptions sun.security.validator.ValidatorException and SunCertPathBuilderException we suggested them to update the Java version in their local system.
But the user mentioned it didn’t helped to resolve the issue.
the exception is sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
we have tried in the recent version of KNIME client as well but facing the same issue.
and that too only for this URL’s.
Please suggest me a solution to resolve the issue.
I’d suggest to check with your network administrators about point (3). To rule out any issues in that regard, try e.g. installing within a different network and see if this solves the problem.
I remember this error from days when KNIME used an even more archaic version of the JVM. AFAIR, I haven’t seen this for a long time. As @qqilihq suggested, please check with your network administrator regarding proxy and content filters.
In the meantime, you (and your user) can download a zipped version of the Palladian update site here:
