我刚刚开始使用 AWS 在 EC2 实例上创建一个 wordpress 网站（使用https://www.youtube.com/watch?v=4WR7EFFLF04）。一切都运行正常，直到我尝试使用另一个教程添加 SSL 证书（我现在似乎找不到）。
在执行这些步骤时，由于重定向次数过多，网站出现问题（假设是 DNS 错误），无法加载。当我返回教程尝试修复我所做的事情时，我发现它让我通过 SSH 登录，而我之前这样做没有任何问题，然后我开始收到“权限被拒绝（公钥）”错误。
从那时起，我就无法登录该实例或任何其他实例，否则会收到相同的错误。我甚至尝试使用全新的密钥创建新实例，但仍然会收到相同的错误。
当我运行启用了详细模式的命令时，它会给出以下输出：

知道发生什么事了吗？
我最初在 stack overflow 上提出了这个问题，但由于偏离主题而被关闭，所以如果这里不是提出这个问题的正确地方，请告诉我在哪里 :)
