-**Possible cause** : This issue might occur if you performed a CodeDeploy all-at-once deployment, and your replacement (green) task set contains bad code that is causing the ELB health checks to fail. With the all-at-once deployment configuration, the load balancer’s health checks start running on the replacement task set _after_ traffic has been shifted to it (that is, _after_ CodeDeploy’s `AllowTraffic` lifecycle event occurs). That’s why you will see health checks failing on the replacement task set after traffic has shifted, but not before.
