Hi all, trying to set up an alb to route traffic to an ec2 instance but its not working. Looking in the AWS web UI I see that the target shows the message “Target is in an Availability Zone that is not enabled for the load balancer”. In the target definition I have “availabilityZone: server.availabilityZone,” but thats clearly not working. Is there a good way to make sure the instance, alb and target all land in the right azs?

I think you also need to make sure the zones of the subnets on the ALB itself align to the zones of your subnets on your instances.

Working with Cameron on this, we are close 🙂
