I can only access my site through the root url but not through a specific route

Site: https://hexhiv.com/

When I try and access the site trough the root url (https://hexhiv.com) the site works fine and i can navigate to any of the routes without issue.
But when I try to access the site directly through a url with a path (https://hexhiv.com/rules) the site wont load and I get a 404 error.

hi there, maybe this is helpful?
