Login attempts to the Cluster Manager may fail after a product upgrade

After upgrading InfoScale, you need to reconfigure any existing secure clusters so that they can use the 2048-bit key and SHA-256 signature certificates. However, even after you successfully reconfigure an existing cluster, login attempts to the Cluster Manager may fail. (3857832)

This issue occurs due to the cached credentials whenever the Cluster Configuration Wizard (VCW) is used to reconfigure a cluster. It does not occur if you configure a new cluster using the VCW after installing the patch.

Workaround: Log off from the system and log in again. You should then be able to log in to the Cluster Manager to perform further operations.
