Calling route() from subdomain return wrong url address?

[whousehomestay]

Hello... I have a problem when calling route() function from sub domain on blade.

My web.php:
Route::domain('creator.'.config('domain.domain'))->name('creator.')->group(function () {
Route::get('/', 'Creator\DashboardController@index')->name('dashboard');
});
Route::get('/', 'Front\FrontController@index')->name('app.homepage');

when I am currently on url: creator.domain and call {{route('app.homepage')}} on blade, it returns creator.domain.com instead of domain.com. Do I need to create a group routing that has 'www' as sub domain? or maybe I miss something there? Thank You...
