Hi, I'm deploying an app on tomcat8 on 2 t3.micro instances hosted both on a private subnets with NAT access to 2 public subnets, and registred as targets on an Application loadbalancer.
My environment works well except that it doesn't receive data from the instances for the enhanced health check.
I've checked /var/log/healthd/daemon.log
and find this error Aws::Errors::MissingCredentialsError) unable to sign request without credentials set. Backing off by 200 seconds in addition to delay interval
as a Warning
when I was assigning public IP addresses to my instances and a classic loadbalancer the health checks pass but now it doesn't.
Is there another config to add in order to make it work ?
Thanks
