Node.js 在构建noone页面加载后部署。只是第一页。反应

我正在使用一个主机“Umbler”，在我完成部署、构建、初始页面运行之后，其他页面不会运行

在开始时，当重定向时，将显示一个空白页。所以我为“找不到”做了一条路线

<Route render={() => <h1>Not Found Page</h1>} />

我试过使用HashRouter和BrowserRouter（我想使用BrowserRouter，但hash也不起作用）

在我要构建的服务器上，我制作了以下创建应用程序文档：

app.use(express.static(path.join('client/build')));

app.get("*", function (req, res){
    res.sendFile(path.join(__dirname, "client", "build","index.html"));
});

请有人帮忙，页面已打开，如果您想测试，路线在这里。 calces.com.br

tks，请帮忙
