SSLPeerUnverifiedException when connecting to the REST endpoint. REST endpoint is using TLS v1.2.

Error Messages Caught unhandled exception: peer not authenticated

Steps to Reproduce

  1. Create a Connect-REST rule.
  2. Create a truststore rule in the Connect-REST rule and import the REST Endpoint certificates.
  3. Execute the Connect-REST to connect to a TLS v1.2 or TLS v1.1 version enabled Endpoints.

Root Cause

A defect in Pegasystems’ code or rules. The out-of-the-box invokeaxis2 activity had the hardcoded protocol value of SSL.


Perform the following local-change:
  1. Ensure the truststore contains the complete signer certificates chain (the Intermediate and the Root certificates)
  2. Edit the out-of-the-box pyInvokeRESTConnector activity.
String protocol = "SSL";
String protocol = "SSL_TLSv2";
