PAM Client upgrade fails around 90% through a VPN or VDI

Products

• CA Privileged Access Manager (PAM)

Issue/Introduction

When updating the PAM client while connected to a VPN or VDI, the update proceeds to 90-95% before it fails and the connection is terminated. When connected directly to the network, the PAM client updates successfully.

Cause

The connection termination is likely caused by TCP optimization settings enabled on the Content Delivery Network (CDN), which may change proxy IPs during the upgrade process.

Resolution

Contact the CDN vendor to request a review of the network configuration or disable TCP Optimization.
