An announcement was made a couple of months ago about the deprecation of .com → .app redirects
Your site will only work on qu33n.netlify.app. It appears you have qu33n.netlify.com hardcoded. You also have the custom domain qu33n.art redirecting to the qu33n.netlify.com. As you have a custom domain configured, the best solution is to use this instead of the assigned .netlify.app (formerly netlify.com) subdomain. That’s the point of custom domains.
