React router private routes / redirect not working

You need to wrap your Route with <Switch> tag

ReactDOM.render(
<Provider store={store}>
    <App>
        <Router>
            <div>
                <Switch>
                   <PrivateRoute exact path="https://stackoverflow.com/"><Home /></PrivateRoute>
                   // ... other private routes
                   <Route path="/login" component={Login} />
                </Switch>
            </div>
        </Router>
    </App>
</Provider>,
document.getElementById('root'));
