Gray environmental conditions of the elastic beanstalk

Question

I deployed the application to Amazon Elastic Beanstalk. But it somehow became Gray States. Now I am faced with a big problem for updating or changing the configuration in this environment. So, how can I make health green from Gray?

Answer 1

He should answer 200 OK, see the document

You can install a key pair during deployment, then find the public IP address in EC2 instances, connect there (see doc) and check manually.
