Hi, I try to add the node “counter generation” from the hub, but get the following error message:
Some sites could not be found. See the error log for more detail.
Unable to read repository at https://update.knime.com/partner/4.6/content.xml.
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

URL can’t be dropped to KNIME workbench
Unknown URL:

I have all admin rights for KNIME

Thansk for your help!

You are using a proxy/firewall/virus scanner that tampers with the encrypted traffic to KNIME’s update site. Therefore you get this error.

Thanks so much - I already read throught possible solutions, but still I can’t fix it. What should I tell our IT to get this solved? Thanks again!

I cannot give you any specific advice - especially since I don’t know what exactly interfers with the traffic - but if your IT department reads the answer they should be able to figure out a solution.

Great - I had to change something regarding the VPN connection and it works perfectly. Thank you!
