A Solutions Architect has deployed an application on Amazon EC2 instances in a private subnet behind a Network Load Balancer (NLB) in a public subnet. The NLB has not been associated with a security group. Customers have attempted to connect from their office location and are unable to access the application. The targets were registered by instance-id and are all healthy in the associated target group. What step should the Solutions Architect take to resolve the issue and enable access for the customers?
