Hi @info3660cbfafe98de158fbe7e,

In order to run Rails server in production mode, you need to use following line:

rails s -e production

However, please notice that Rails assumes that you have your files precompiled for production environment. If you want to change this and have compiling during runtime in production you must change config.assets.compile in config/environments/production.rb to following:

config.assets.compile = true

If afterwards you still are experiencing the issue, I’ll suggest checking out your logs to see the exact reason behind the error.
