Getting "sun.security.validator.ValidatorException: PKIX path building failed:" error while calling HTTPS service even after uploading the client certificate in Admin console.

Hi,

Am calling an external HTTPS service through integration object and while executing the integration object am getting the below error

Failed to connect to 13.92.186.254:9443/.../token" detail: "sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I have uploaded the client certificate (Admin console -> Client Certificates) which I have received from the target system but even after uploading the client certificate in Appian, while triggering the service am getting the above error.

Can anyone help me understand, after uploading the Client Certificate in Appian do I need to pass any of the reference of the uploaded certificate (Serial Number, Thumbprint) with the REST call request.

Any help is much appreciated.

 

Regards,

Balaji.R
