User cannot download files using Talend Open Studio Application with WSS agent

Products

• Cloud Secure Web Gateway - Cloud SWG

Issue/Introduction

Users accessing internet via WSS agent

Talend Open Studio App downloaded to Windows host running WSS agent

User can connect to the Talend Open Studio back end

User unable to download the files inside talend application

Environment

WSS agent on Windows

Talend Open Studio Application

Cause

Certificate pinning issue with application

Resolution

Add an SSL interception bypass for the following two domains:

-         talend-update.talend.com
-         update.talend.com

 

 

Additional Information

With SSL interception enabled, the Application receives the WSS minted certificate and not that from the back end Web server. If the client is setup to only accept certificates from the back end web server, chcks will fail. In this case here, the application has multiple layers and the initial connection to the Studio back end had no issues. Only when the code handling the file downloads was activated did we see the issue.
