我剛開始使用 AWS 在 EC2 執行個體上建立 WordPress 網站（使用位於https://www.youtube.com/watch?v=4WR7EFFLF04）。一切都工作正常，直到我嘗試使用另一個教程添加 SSL 證書（我現在似乎找不到）。
在執行這些步驟時，由於重定向過多，某些內容破壞了網站（假定為 DNS 錯誤），導致無法載入。當我返回教程試圖修復我所做的事情時，我到達了它讓我通過SSH 登錄的地方，而我之前沒有遇到任何問題，但我開始收到“權限被拒絕（公共密鑰）”錯誤。
從那時起，我就無法登入該實例或任何其他實例而不會出現相同的錯誤。我什至嘗試使用全新的密鑰創建一個新實例，但仍然遇到相同的錯誤。
當我在啟用詳細資訊的情況下運行該命令時，它會給出以下輸出：

知道會發生什麼事嗎？
我最初在堆疊溢出上有這個問題，因為偏離主題而被關閉，所以如果這不是這個問題的正確位置，請讓我知道在哪裡:)
