Wildcards BrowserRouter Intercepted External 404 Page

[jyxjjj]

I don't want React handles paths out of Routes,
So i used

<Route path='*' Component={()=>{
window.location.href='/404.php';
return null;
}} />

(Of course i tried <RealComponent/> that contains useEffect, replace , assign , history.push, useNavigate, and so on.)
When i input /404.php in address bar and press enter, i can successfully access it.
That means Nginx was set correctly.

When i input a non-exist path such as /hello, Nginx tried to return React, then React catches it.
Until now, it is okay and should be like this.

Normally, React should jump to /404.php,
But, URL in address bar changed to /404.php, and React still searching if there's a Route matched.
Then it find it cannot match. Redirect to /404.php again. Match again. And then again and again.
