Hi…
i have the same problem… so i did what you said in the post ( See Image1 of the certificate in the cacerts file

but the problem persist in the workflow:

ERROR Twitter Search 0:2 Execute failed: sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Any idea??

thank you

You are no trying to connect to a KNIME Server but to Twitter (the error message comes from the Twitter Search node). This topic is about connecting to a KNIME Server.
Since I assume that Twitter uses a certificate that is accepted by almost anyone my guess is that there is a proxy or firewall between the workflow and Twitter which tries to sniff the encrypted traffic and presents a forged Twitter certificate.
