SSL Webrick on localhost not hosting ruby on rails app

Question

How do I get Ruby On Rails Webrick to work with self-signed SSL certificate on localhost just to test https ? Basically, Ived followed the work that has been done here: Configure WEBrick to use automatically generated self-signed SSL/HTTPS certificate

And produce the script like the following:

require 'webrick'
require 'webrick/https'

cert_name = [
  %w[CN localhost],
]

server = WEBrick::HTTPServer.new(:Port => 8000,
                                 :SSLEnable => true,
                                 :SSLCertName => cert_name)


# Shutdown gracefully on signal interrupt CTRL-C
# http://www.ruby-doc.org/core-2.1.1/Kernel.html#method-i-trap
trap('INT') { server.shutdown }

server.start

When I tried to access https://localhost:8000/, it did warn about trust but just went ahead, instead I had nothing come out but this. BTW, https works fine, just it seems its not getting the right route for SSL.

The reason your server is returning that 404 is because the script you've set up is just for an empty WEBrick server; it doesn't actually mount your Rails app. The thread you linked to seemed to be using that script just as a minimal test for the SSL functionality. The full answer to getting WEBrick to work with SSL looks to be answered here: How do you configure WEBrick to use SSL in Rails?

However, I wouldn't recommend you bother. WEBrick is strictly meant as a development-only server, and isn't suitable for use in production (which is why it's hard to get it to do things like use SSL). Instead, either set up nginx as a SSL-serving proxy to your app or use a server which supports SSL easily, like thin does.
