Open Workbench Shows Error 'handshake_failure'

Issue/Introduction

When trying to open a project in Open Workbench, the following error is shown: "A server error occurred during login: - Received fatal alert: handshake_failure".

Cause

This is caused by incompatible cryptographic algorithms between Open Workbench and Clarity PPM.

This is likely because a mismatched (and old/unsupported) version of OWB is in use, and Clarity PPM has been configured to use only TLS 1.2. Older versions of OWB shipped with old versions of Java.

Resolution

Check that the version of OWB match the version in Clarity PPM, and that they are both supported:

• Clarity PPM: Click on the About link, in the top right corner, and look for the 'Version/Build'
• Open Workbench: Click on the blue 'i' icon in the top right corner, and look for the version number inside the parentheses.

If you are using a current and supported version of Clarity PPM, please download the matching version of OWB by going to Home > Personal > Account Settings > Software Downloads.
