Laravel 5.3 sometimes return different 404 page -

i'm trying understand why 404 page not loading if try go under public folders.

when i'm trying go assets folder. i'm getting 404 page.

make sure views placed inside resources/view folder.
when run laravel in local pc or server, run administrative privileges (not must thing)

sudo php -s localhost:8888 -t public 

this use in linux. think missing here.
