Hi
Whether page is published or not, preview returns 404 - Page Not found.
Pages work when viewing in normal mode.

A browser window displays a "Page not found" message at the URL localhost:4434/umbraco/preview/?id=2656, accompanied by a console error indicating a failed resource load with a 404 status. (Captioned by AI)
