Router react tidak berfungsi di hosting

Aku coba belajar react trus pada saat upload ke hosting routernya tidak berfungsi, sementara di localhostnya normal , apa ada yg bisa bantu errornya dimana ? ini contoh kode routernya :

import React from 'react'; import { BrowserRouter, Route, Switch } from 'react-router-dom'; import Welcome from './components/Welcome/Welcome'; import Home from './components/Home/Home'; import Login from './components/Login/Login'; import Signup from './components/Signup/Signup'; import NotFound from './components/NotFound/NotFound';

const Routes = () => (

); export default Routes;
