Guest portal authentication not working #101

Hey, I have a problem with the authentication:

I've tried to create an external captive portal with the API, the auth_guest_basic.php file as template (and config.php) and the following settings:

Guest Hotspot
Guest Portal enabled
Authentication Type "External Portal Server"
IP of local portal page
Local Account with super admin as login account

My Setup:

UDM Pro (Firmware Version 1.8.6.2969, UniFi Network Version 6.0.43)
Multiple UAC AP Pro's (Firmware Version 4.3.28.11361)
Portal Server running on a Raspberry Pi 3 B+

Now my problem: When the guest is redirected to the portal, the output is "false".

I've already tried to google the problem. I saw a post and tried the code from there. Exactly the same code.
And in Debug-Mode, I see following:

-----------LOGIN-------------

I hope anyone could help me.

Ok, to start with the controller URL is missing the https:// prefix.

Please provide some more details such the contents of the config.php file (without the password...) and how you are capturing the device and AP MAC addresses.

Okay, here are the files:

config.php:

/**
 * Controller configuration
 * ===============================
 * Copy this file to your working directory, rename it to config.php and update the section below with your UniFi
 * controller details and credentials
 */
$controlleruser     = '************************'; // the user name for access to the UniFi Controller
$controllerpassword = '***********'; // the password for access to the UniFi Controller
$controllerurl      = '192.168.0.1'; // full url to the UniFi Controller, eg. 'https://22.22.11.11:8443', for UniFi OS-based
                          // controllers a port suffix isn't required, no trailing slashes should be added
$controllerversion  = '6.0.43'; // the version of the Controller software, e.g. '4.6.6' (must be at least 4.0.0)

/**
 * set to true (without quotes) to enable debug output to the browser and the PHP error log
 */
$debug = true;

index.php:

<?php

//PHP SCRIPT FOR SIMPLE PORTAL
//REQUIREMENTS:
//curl needs to be enabled (php_curl.dll for widnows)

session_start();

$_SESSION['id'] = $_GET['id'];          //user's mac address

authorized.php:

<?php

session_start();

Hi, I have a UDM PRO in which I am configuring a Hostpot Portal, in the redirection settings of the UDM I configured an external server, this external server is an API that I configure with Node JS to receive the connection requests to then show the user a form where he registers his data, up to this point everything works correctly, the problem I am having is when authorizing the user on the network to browse the internet I don't know if I should send any http response to the UDM then I need help with this.

The connection request that arrives to the external server when someone connects looks like this:

How do I authorize the user or what response should I send to allow the connection?

This question is not really related to the API client. It is more about how to build a captive portal.

I will leave this comment here, maybe someone can contribute some suggestions.
