Problem Statement

When using Redis for session storage, the session expires exactly 30 minutes after login even when actively using the backend.

Steps to Reproduce

Configure Redis session storage with

TOMCAT_REDIS_SESSION_ENABLED="true"
TOMCAT_REDIS_SESSION_HOST
TOMCAT_REDIS_SESSION_PORT
TOMCAT_REDIS_SESSION_USERNAME
TOMCAT_REDIS_SESSION_PASSWORD
TOMCAT_REDIS_SESSION_SSL_ENABLED="true"
TOMCAT_REDIS_SESSION_PERSISTENT_POLICIES="DEFAULT"

Log in and set a timer. You will be logged out in 30 minutes even if you click around the backend more recently.
