Certificate Error in Analyze

If you get the below error while running nodes: 

Execution Error: Unexpected error occurred during processAll while running the node: feign.RetryableException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

You need to import the certificate, please see this document on how to do so, under the section "installing the certificate": https://doc.infogixsaas.com/analyze/Default.htm#h-tech-guides/adding-SSL.htm
If there is more than one certificate in the path then each one should be imported to the cacerts keystore. You should click on the padlock to the left of your Analyze URL and see what the path looks like.

If it has 3 levels, then export all 3 individually and import individually to cacerts.

With all 3 imported the error should disappear. 

Also, attaching the screenshot of the error code for reference:
