Error on login to server from KNIME application

KNIME Server
1

Hey everyone,

We changed the certificates on our KNIME Server. I stored the new certificates in my java cacert-store. In KNIME if I try to login to the server over the KNIME Explorer I get the following error:

"Connecting to server "https://knime-server:8443/tomee/ejb" failed.
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"

Does anyone have an idea what this could be caused by?

Thanks for any hints,

Daniel

KNIME doesn't know you server's certificates. To which cacerts file did you add them? Note that KNIME has it's own JRE and therefore you must add any custom certificates to its cacerts file.

You're a genius! Of course that's what I'm missing!.

Thank you very much!
