Why doesn't my ReactJS app work?

Question

React

I will describe briefly, the application on ReactJS does not work.
The problem is, when I use "npm run build" it is going to my "build" folder, after which I take any hosting and launch the site through Filezilla, the first page of the site works, but I cannot go to the rest of the pages, it says that " The requested URL was not found on this server." prescribed a bunch through react-router-dom.

I suspect that the problem is on the hosting side. Share any ideas on how this can be solved, I will try everything.
