This issue could be due to defect/misconfiguration in the operating environment.

"pyInvokeRestConnector" activity was setting the SSL protocol to SSL when the service expected a TLS protocol during the SSL handshake.

Note:- Connect-REST rule has been enhanced in Pega 7.1.8 where you, as an application developer, can pass in the SSL protocol at PRPC level.

Suggestion:

Override the pyInvokeRestConnector activity into the local ruleset. Modify Java code in Step 4,

Change the following line:

String protocol = "SSL";  TO String protocol = "TLS";

Note:- This issue is fixed in Pega 7.1.8.

Reference:- Restful services fail with SSLPeerUnverifiedException.

If it didn't get resolved with above changes,

Do you have enabled DSS https/allowAllHostnames? Try disabling and re-run the use-case.

Still, if it's not working enable following JVM argument -Djavax.net.debug=all and provide us with the server logs.

Reference:-  javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
