Steps to Reproduce



Not Applicable

Root Cause



The root cause of this problem is defect/misconfiguration in the PRPC 6.3 SP1 operating environment. Connect-REST calls in PRPC 6.3 SP1 use the default JVM trust store, cacerts. Hence, the appropriate trusted certs and root certs need to be installed in JVM's cacerts trustStore found in jre/lib/security folder.


Resolution



Update the default JVM trust store in jre/lib/security folder (cacerts) with appropriate trusted certs and root certs for successful SSL communication.
