Laravel 5.6 wildcard route not functioning as expected with domain

I'm using Laravel 5.6 and am trying to create a laravel route in my web file so that anything with the following URL: /assets/* would go through my controller. For instance, /assets/page1/page2 or /assets/js/somefile, for some reason it only works when I literally type the following into my URL: /assets/*.

Route::get('/assets/*', 'AssetsController@proxy');

Where am I going wrong?
