Issue/Introduction

When using the HTTP POST Operator in PAM against an HTTPS URL, the following error appears:

IO Error or connection aborted while executing request or processing HTTP response. class javax.net.ssl.SSLHandshakeException. Received fatal alert: handshake_failure

This error does not occur when using SOAP UI.

Environment

Process Automation Manager v4.3.05 and up

Cause

Possible causes include:

• JDK version being used is unsupported
• Could also be caused by a timeout failure

Resolution

1. Confirm the JDK version are supported for your PAM Version: Platform Support and Requirements
2. If the installed version of JDK is unsupported, upgrade a supported version following steps noted in the following document: Update JDK being used in Process Automation
3. If this does not resolve the problem, check to see if there might be a timeout failure in the application that is using the Rest API to communicate with ITPAM.  If this is the case, adjust the application's timeout settings to allow enough time to complete the handshake.
