Auth::user(), Session and Cookies are not carry over

[ginndee]

I created a page that that has Auth::user() to get the information i need in that page. but it redirect to login page although the page that will generate into image is also authenticated.

Here is my code for the html that will convert to image

		$cookie = Cookie::get('category');

		if (!$cookie) {

				return redirect()->to('public/' . $category);

		}

		$user = Auth::user();
		$category = !empty($category) ? $category : $cookie;

		if (!$user) {

				return redirect()->to('/survey/' . $category);

		}

             return view('multi-preview', compact('user', 'category'));

And here is the controller for convertion

		$options = [
			  'width' => 1080,
			  'quality' => 90
			];
    		$conv = new \Anam\PhantomMagick\Converter();
    		$conv
    					->source(url('/image/'.$category))
    					->setBinary('C:\phantomjs\phantomjs')
    					->setImageOptions($options)->toJpg()->save('/images/google.png');
				$conv->serve();
