如何调试 Apache2 的 500 服务器错误？

最近，每当我尝试通过互联网（SSL、DuckDNS、Apache2）访问我的家庭自动化系统时，我都会收到 500 错误。如果我通过 SSL 在本地访问我的家庭自动化系统，它就可以正常工作（https://本地IP:端口)。我还有另一个网页使用相同的设置（SSL、DuckDNS、Apache2），甚至在 Apache 中使用相同的 VirtualHost。奇怪的是，那个网页运行得很好。

我尝试检查 Apache 的端口 443 错误日志，但它让我毫无头绪。我尝试进行一些搜索，但我只找到“检查您的脚本，它们必须是可执行的”。我个人没有更改任何可能导致此问题出现的内容，但我怀疑 Apache 已通过 unattendedupgrades 更新，可能导致此问题。

我在下面附上了错误日志的一部分，该日志是在尝试从家庭自动化系统访问 JSON URL 命令后创建的。据我所知，第一个条目立即出现 500 错误，所有其他错误都是未找到错误，因为它正在尝试从其他页面加载资源（该页面正在运行，但需要不同的 URL）。

我该如何调试此问题？
