Completely shut down for dash and shows a Error page when the pageshuts down

I have a dash app that I usually expose to users every day during the day and would shut down the app (using task scheduler) at night. Is it possible that, when the app is not running, the webpage could be showing an error page prompting users to refresh the page. It is because it seems like when I restart the tool, the callbacks on those websites could still work and I want users to completely refresh the page as new values would be automatically loaded.
