    A few places to look are:
    myapp/current/log/production.log
    replacing myapp with the name of your app.
    Other logs will be located in /var/log - particularly /var/log/syslog

You need to look in your app directory logs for puma or webserver. I just had this and found this message:

Rack app error: #<RuntimeError: Missing `secret_token` and `secret_key_base` for ‘production’ environment, set these values in `config/secrets.yml`>
