Hi!
I am Japanese. I am not good at English, so I apologize if my writing is poor.
I created my own Dockerfilet and docker-compose.yml and created a Rails 7.0.4 app with a Docker built environment.
I got a message that fly deploy was successful, but when I fly open, I get an error and I am not able to deploy!

2023-05-06T00:03:38.197 health[be5a64ec] nrt [info] Health check on port 3000 is now passing.
I got a message that the deployment was successful, but I am not able to display it on the screen because of the following error.
Health check on port 3000 has failed. Your app is not responding properly. Services exposed on ports [80, 443] will have intermittent failures until the health check passes.
I referred to the Reference Articles but could not find a solution.
I would like to know if there are any possible causes.
Is there anything in the following code that needs to be corrected?
