Vote B! Target.FailedHealthChecks Verify that the target is listening for traffic on the health check port. You can use the ss command on Linux targets to verify which ports your server is listening on. For Windows targets, you can use the netstat command. https://aws.amazon.com/premiumsupport/knowledge-center/elb-fix-failing-health-checks-alb/
