Change health check URL in EBS

Question

I copied an EBS environment and was showing severe health because the environment was not pinging /healthCheck. I couldn't find where to change the "health check URL" so I updated the server to response with 200(OK) on root /

Now I'm getting Cloudwatch logs with 404 responses on /healthCheck....grrr. It's like EBS is pinging /healthCheck but listening on root /. How can I fix this?

Answer

In Beanstalk console this is in Configuration -> Modify Load Balancer (or something like that).
You didn't say what type of load balancer you are using, but here is the link for ALB configuration. CLB and NLB you can find right next to it.
