Why isAuthenticated return false when I am loggedin


I’m trying to restrict a page to only logged-in users using the code below. However, even when I believe I’m logged in (based on the state and code present in the URL, and because I’m redirected to the after-login page), the isAuthenticated method consistently returns false.

I’ve enabled session_auto in my php.ini, but I suspect the issue may be related to sessions. When I check, I don’t see any active PHP sessions after logging in—only cookies. Can you advise on how I might debug this?


// Check if user is not authenticated
if (!$sdk->isAuthenticated()) {
    // Redirect user to Auth0 login page
    $loginUrl = $sdk->login();
    header("Location: $loginUrl");

Thank you.
