To address the issue where an unauthorized request to http://127.0.0.1:8080/rb/admin results in a 404 error instead of routing to the desired path, you need to ensure that your Rails application is correctly configured to handle requests with the /rb prefix. Here are some steps you can take:

1. Ensure Rails is Aware of the Prefix:

   In your application.rb file, you have already set the config.action_controller.relative_url_root to /rb. This is correct, but ensure that this setting is being applied correctly in your environment.

2. Check Your Routes:

   Make sure that your Rails routes are set up to handle requests with the /rb prefix. You might need to adjust your routes to account for this prefix. For example, you can use a scope in your routes.rb file:

   Rails.application.routes.draw do
     scope '/rb' do
       # Define your routes here
       get 'admin', to: 'admin/dashboard#index', as: :admin_root
     end
   end

3. Nginx Configuration:

   Since you are using the Nginx configuration without the rewrite rule, ensure that your Rails application is prepared to handle the /rb prefix. The Nginx configuration you provided should look like this:

   location /rb {
      proxy_pass http://ruby:3000;
      
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $scheme;
   }

   This configuration forwards requests with the /rb prefix to your Rails application. Ensure that your Rails application is correctly interpreting these requests.

4. Rails Controller:

   Ensure that your Admin::DashboardController is set up to handle the index action. It should look something like this:

   class Admin::DashboardController < ApplicationController
     def index
       # Your code here
     end
   end

5. Testing:

   After making these changes, restart your Rails server and Nginx to apply the new configurations. Test the URL http://127.0.0.1:8080/rb/admin to ensure it routes correctly to the admin/dashboard#index action.

By following these steps, you should be able to resolve the 404 error and have your application route requests correctly. If you continue to experience issues, double-check your environment variables and ensure that all services are running as expected.
