QNetworkInformation::isBehindCaptivePortal() incorrectly returns false on MacOS

GelaMalekPour

Hey all,

I would like to use QNetworkInformation::isBehindCaptivePortal() to determine if the network is behind a captive portal. When I test my code, it is always coming back as false even when I am in fact behind a captive portal (network is connected but not yet authenticated). I'm on MacOS Sonoma 14.1 which I believe is a supported platform. Is this a genuine bug or am I missing something? Where can I find a list of all supported platforms?

Here's the relevant snippet:

    if (QNetworkInformation::instance()->isBehindCaptivePortal()) {
      emit activationBlockedForCaptivePortal();
      Navigator::instance()->requestScreen(MozillaVPN::ScreenCaptivePortal);

      m_portalDetected = false;
      return true;
    }

Good morning,

The documentation isn't clear about which platforms are supported wrt captive portal detection.
It's supported for Android, Glib, Networkmanager (DBus) and Networklistmanager (on Windows, if QT_FEATURE_networklistmanager is enabled).

Detection support for Apple platforms hasn't been implemented (yet). That's why it returns falsealways.

Cheers
Axel
