My Elastic Beanstalk application stopped working. The health is "No Data". The EC2 instance that supported the application has been deleted and I don't know why

0

I just logged into my account to find that my EC2 instance that was associated with my Elastic Beanstalk application was deleted. I still have an active RDS instance that was associated with the application, but I don't know what caused the EC2 instance to disappear.

Hello.

I believe Elastic Beanstalk's EC2 is managed by AutoScaling.
We believe that the EC2 instance was terminated as a result of the Auto Scaling group health check or ALB health check determining that the EC2 instance was abnormal.
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.managing.as.html

If you look at CloudTrail, you can probably see the API history where EC2 has been terminated.
If you want to start it, I think it will start if you adjust the number of EC2 units in the AutoScaling group etc.

    That does appear to be what happened. It actually corrected itself and spun up the EC2 automatically some time after I posted the question. Thank you.
