Django not serving static files with even after collectstatic

Question

i'm having problems with django static files in production.I know django requires that you collectstatic during deployment, which i did. The real problem comes when i try to access my page on the browser and i get a 403 forbidden error on all static files. I tried changing my permissions and ownership of var/www/html folders to 755 and files to 644 but still no luck. How do i make my static files load?
