HashRouter not working on server?

Question

React

Good afternoon. Uploaded the app to firebase. But hashrouter stops working after reloading with nested navigation. I run it on a PC - everything is fine - as it should, I upload it to firebase - nested routes work, but if you go along the route (it works correctly) and then refresh the page, it will show 404. I tried it with BrowserRouter - the same garbage. I emphasize that the main routing works well, and the nested one (for which we are talking) works as described above.
In the navigation, the second picture is the section in which the problem is:
