子域名一直指向主域名并出现 404

我有一个问题，我有一个主域名网站（例如示例.com和子域名.example.com)。example.com 安装了 WordPress，而子域名安装了 php 应用程序。我可以毫无问题地访问 WordPress，但是当我访问子域名.example.com它只显示 WordPress，当我打开subdomain.example.com/index.html它只是返回 404。

我的服务器运行在非常干净的 Ubuntu Server 22.04 上，运行 Apache2、MariaDB 和 php。我的 DNS 通过 Cloudflare 托管。我的 DNS 设置正确，包括 A 名称等。除了基本操作外，我并没有做太多事情

我不知道自己到底错在哪里。

答案1

看起来，在您的 SSLvhost部分中，您没有ServerName、ServerAlias或DocumentRoot指令。如果您的网站配置为重定向到 SSL，则只有在重定向到 SSL 后，您才会获得默认网站，而这显然是您的example.com网站。
