Error: unable to find valid certification on AWS Connection

Hello,

I’m using Amazon Authenticator + S3 Connector to connect to my S3, but I’m getting an error about the certificate

ERROR Amazon S3 Connector Execute failed: Unable to execute HTTP request: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I’ve tried to change knime.ini, adding these two lines:

-Djavax.net.ssl.trustStore=NONE
-Djavax.net.ssl.trustStoreType=WINDOWS-ROOT

But when I do this, my Redshift connector throws another error:

ERROR Amazon Redshift Connector Execute failed: Error loading the keystore NONE.

Could anyone help me with this?

I’m using version 5.4.0

Thank you!
