A company has deployed a new web application on Amazon EC2 instances within private subnets across three Availability Zones, fronted by an Application Load Balancer (ALB). Security auditors mandate encryption for all connections. The company utilizes Amazon Route 53 for DNS and AWS Certificate Manager (ACM) for automated SSL/TLS certificate provisioning, with SSL/TLS termination occurring at the ALB. During testing with a single EC2 instance, no issues were observed. However, after deploying to production, users report being able to log in but are unable to use the application, as each new web request forces a restart of the login process.
