Getting error "sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException" while accessing WSO2 URL

Hi All,

We were accessing a third party URL of a WSO2 Identity server (13.92.186.254:9443/.../token) through Appian’s Integration object to get a OAuth token. And while testing the URL we are receiving the below error.

Error Message:

 Failed to connect to xx.xx.xxx.xxx:9443/.../token sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Can anyone let me know if you have faced this kind of error before.

Regards,

Balaji.R
