System.CalloutException: sun.security.validator.ValidatorException: PKIX path building failed

I've integrated with the EnergyStar API,


The calls to the System Working until recently I've been receiving this Error


System.CalloutException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target


I tried looking through forum posts

  1. https://success.salesforce.com/answers?id=90630000000gq6JAAQ
  2. http://boards.developerforce.com/t5/Apex-Code-Development/callout-exception-PKIX-path-building-failed/td-p/99751
  3. http://boards.developerforce.com/t5/General-Development/System-CalloutException-sun-security-validator/td-p/549159

but Did not get me anywhere


  • Is this issue because of the Changes in Energy Star Severs 
  • Does Winter 14 release changed the certificate rules?
  • Because the integration was working fine till a while ago, and nothing in the system has changed.

Any  help is deeply appreciated !
