我那时，我现在无法解决问题了……说真的，我太愚蠢了，检查了letsencrypt ssl并同时创建了一个自签名证书。但是，我认为我已经破坏了 SSL 配置。其他使用letsencrypt的域，除了一个域/网站，即使在新创建它之后也是如此。我在下面打印的日志之外找不到日志。
以下是error.logApache2的：

这就是我的 error.log 试图让我说的，但它已经与其他域一起使用。我认为必须有一个配置，它试图获取或任何旧证书。Letencrypt 显示没有错误，并且来自 ispconfig 的 server.sh 也没有错误。
我在 ispconfig 中重新创建了网站/域，但我仍然得到同样的错误。其他域完全没有错误。我真的很确定，问题出在检查letsencrypt并同时创建证书。
我通读了 .vhost 中的配置，但 ssl 部分中没有任何内容...
