Trouble with "Setting up the back end server" in Online Unlock Status Tutorial

Audio Plugins

I’ve been trying to follow this tutorial: https://docs.juce.com/master/tutorial_online_unlock_status.html
I’m using Ruby on Rails for the server-side implementation, but I’m running into an issue during the “Setting up the back end server” step. Instead of receiving the expected “Sorry, we were not able to authorise your request.” message, I keep getting a “Couldn’t connect to…” error message.

What might I be doing wrong?

Here’s my setup so far:
routes.rb

Rails.application.routes.draw do
  post "authorization", to: "authorization#create"
end

authorization_controller.rb

class AuthorizationController < ApplicationController
  def create
    send_response
  end

  def send_response
    # Build the XML response
    response = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"

    if params[:email] == "test@example.com" && params[:pw] == "test"
      response += "<MESSAGE message=\"Thanks for registering our product!\"><KEY>INSERT_KEY_HERE</KEY></MESSAGE>"
    else
      response += "<ERROR error=\"Sorry, we were not able to authorise your request. Please provide a valid email address and password.\"></ERROR>"
    end

    # Set the content type to XML
    render xml: response, content_type: "text/xml"
  end
end

In my class that inherits OnlineUnlockStatus, I’ve overridden the getServerAuthenticationURL() method as follows:

juce::URL getServerAuthenticationURL() override {
	return juce::URL("https://localhost:8443/authorization");
}

Am I missing something in the configuration, or is there an issue with how I’m setting up the URL or server-side handling? Any guidance would be greatly appreciated!

I managed to solve the problem!

The issue was resolved after I properly implemented readReplyFromWebserver in my JUCE plugin to handle the server’s response correctly. Additionally, I temporarily disabled CSRF token authenticity verification on the Rails server to allow the plugin’s POST requests to be processed without issues during development.
