Nginx and Unicorn) Cannot access local server

Question

After deploying my Application(Ruby on Rails) to Heroku using Nginx and Unicorn, I cannot access local server.

When I run 'rails s' command:

% rails s
=> Booting Unicorn
=> Rails 5.2.4.5 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
I, [2021-02-24T21:38:31.580195 #65055]  INFO -- : unlinking existing socket=/tmp/nginx.socket
I, [2021-02-24T21:38:31.580518 #65055]  INFO -- : listening on addr=/tmp/nginx.socket fd=15
I, [2021-02-24T21:38:31.582319 #65055]  INFO -- : master process ready
I, [2021-02-24T21:38:31.583415 #65069]  INFO -- : worker=0 spawned pid=65069
I, [2021-02-24T21:38:31.584169 #65069]  INFO -- : worker=0 ready

Accessing 'http://localhost:3000', I got 'Cannot access this page. Access denied at localhost' or something like that(Original message appears in Japanese).

With the message 'Booting Unicorn' I know that local server switched from Puma to Unicorn, but no idea about the error reason cause I got no error messages.

If more information needed I can provide.

I'm new to Nginx and Unicorn, so any help would be greatly appreciated.

to make it easier to get an answer it's better to add more details like the configuration files — M.Elkady

Problem solved when I moved the gem 'unicorn' under production environment. After this, I run 'rails s' command and Puma booted up, finally I can access local server.

Thank you so much!
