When configuring the App Layering Provisioning Services (PVS) Agent on the PVS server, the error "Could not create SSL/TLS secure channel" occurs.

Upgrading the App Layering PVS Agent to version 4.4+ will resolve this issue.

This issue can also be confirmed within the logs on the PVS server. Check these logs for something similar to the following to confirm:

C:\Program Files (x86)\Citrix\Agent\Logs

• The first line in the logs will contain the version of the App Layering Agent you are running - Versions below 4.4 will experience this issue
