EC2 upgrade fails and rollsback

0

Hello,

I have been trying to upgrade an instance type for some time, but it becomes stuck at "Still waiting for the following 1 instances to become healthy: (instance id)". It has given a reason null for rollback once and then: Received 0 SUCCESS signal(s) out of 1. Unable to satisfy 100% MinSuccessfulInstancesPercent requirement, so I am not really sure what this means. My instance has never been healthy to begin with, but it was working fine (I still have to understand why is not healthy).

Could that be the reason?

Thanks.

Well, if anyone had this very same problem... well, yes. It was because it was never healthy. I deployed a WebSockets only server, so it was not handling any http requests over '/'. So elastic beanstalk would consider it dead because it was failing the health check. Once I created an end point, elastic beanstalk could request and get its 200 status code, I managed to upgrade my instance type.
