Your company is utilizing an internet-facing load balancer within a VPC. The public DNS name assigned to this load balancer is myDns-1234567890.us-east-1.elb.amazonaws.com. When client applications initially load, they capture the load balancer's DNS name and resolve it to an IP address to directly reference the underlying IP. Despite the client applications functioning properly at first, they unexpectedly cease to work after some time. What could be the reason for this behavior?
