My site access is only for registred users, then when you try to access drupal returns the "access denied" page. I want to customize my "access denied" page but the anonymous user doesn't have the "View published content" permission. Then they can't see a basic page node with my access node page customization.
How can I resolve this ? -It can be a static html (but I don't know how to redirect when this error is raised). But drupal throws an error when I put in /admin/config/system/site-information because isn't a drupal path -If is a node (my access denied page) how can I grant the anonymous users to view ?
I'm using Drupal 8
