AWS EC2 instances are "Out of Service" after getting registered with ELB
amazon-ec2, amazon-web-services
Solution
Is your instance behind the ELB running a web server ? If it is does it return an '200' (OK) ? If not then that's your problem.
If you are running a web service that returns a 200, is your security group open to the ELB? Meaning the ELB's source security group has to allowed into your instance's security group.
Problem
I am facing a problem in AWS. I am creating and registering an instance with an ELB. Though it is getting registered, it is not passing through the health check and showing Out-of-Service. The error reason is "Instance has failed at least the Unhealthy Threshold number of health checks consecutively". My health check values are as follows: ``` Ping Target: TCP:80 Timeout: 10 seconds Interval: 24 seconds Unhealthy Threshold: 6 Healthy Threshold: 10 ``` Appreciate your help. Thanks, Chandan
