There is an error when I log in to Google to connect to Google spreadsheet.(Google Authentication)

When I try to log in to Google from ‘Google Authentication’, an alarm window like below appears, so I can’t log in.
Is there a solution?

Authentication failed: SunCertPathBuilderException: unable to find valid certification path to requested target

This can happen if you are behind a proxy or you have a local virus scanner that tries to break the encrypted communication between KNIME and Google and presents an unknown certificate.


The company is using zscaler for security. Is there a solution?

You can try to add the certificate of your firewall solution to AP’s certificate store. This is described in the KNIME Server documentation, section Client configuration.
