Root Cause

The root cause of this problem is defect/misconfiguration in the operating environment.

There were library compilation errors in the startup part of the logs,
After fixing the function issue we saw another error “ peer not authenticated”. This issues normally arise when correct certificates are not imported on to the JVM’s truststore.


This issue is resolved through the following local change:

The library compilation errors was resolved by
  1. Resaving the calling activity to the latest available ruleset,
  2. Restarting the Nodes after deleting pega temp dir and Pega Extract Marker file.
The “ peer not authenticated” error was resolved by copying the correct cacerts keystore and setting the following JAVA_OPTIONS variable in setDomainEnv.bat file
set JAVA_OPTIONS=%JAVA_OPTIONS%<<Keystorepath>><<password>><<truststorecertpath>><<truststore password>>
