UniFi External Captive Portal - Mobile WiFi Disconnects on Auth
The creator of the repo responded to me. A few lines were un-necessary. The working code looks like this:
$unifidata = new unifiapi($controlleruser, $controllerpassword, $controllerurl, $site_id, $controllerversion);$set_debug_mode = $unifidata->set_debug($debug);$loginresults = $unifidata->login();$auth_result = $unifidata->authorize_guest($mac, $duration);return $auth_result;
