worked for me. For Firefox only.

For a universal solution is adding the headers both in the login route and the redirect to home

Route::get('/login', function () {
    return response()
        ->view('auth.login')
        ->header('Cache-Control', 'no-store, no-cache, must-revalidate, max-age=0')
        ->header('Pragma', 'no-cache');
})->middleware('guest')->name('login');;

Also it needs to never have cached the page. If you test it while your browser has cached the logic route it will never work. Just go to a new tab.

You need to pass an array to it I guess

Route::group(['namespace' => 'Admin', 'prefix' => 'admin', 'middleware' => ['auth.basic', 'auth.admin']], function() {});

If that doesn't work you have to split them I guess

Route::group(['middleware' => 'auth.basic'], function () {
    Route::group(['namespace' => 'Admin', 'prefix' => 'admin', 'middleware' => 'auth.admin'], function() {
        
    });
});
