Root Cause
The environment changed 'Affinity cookie time to live' was set from '0' to '3600'. This caused the end-user session, after an hour, to be subject to load balancing again, with the possibility of obtaining an incorrect node on requests that occurred after the cookie had expired.
When the issue occurred, the End User portal refreshed and redirected the user back to the default portal. The desktop level Single Sign-On (SSO) authentication was used. Hence, login screen did not display.
Resolution
The Pega Platform requires Session Persistence to the same JVM node. Setting a Time to Live, an expiry, on an Affinity cookie causes the user sessions to refresh intermittently.
As a local-change, revert the 'Affinity cookie time to live' to '0'.
