- 錯誤型別：
- 其他錯誤
- 錯誤名稱：
- 无法通过SSH或SFTP连接服务器
- 英文名稱：
- Host key verification failed
- 錯誤描述：
- 这通常是因为IP地址或SSH密钥指纹已更改（通常是由于服务器更新），而旧的仍存储在您的known_hosts文件中，该文件用于SSH和SFTP连接。
通過SSH或SFTP連線時遇到問題？如果您收到如下所示的錯誤，這通常是因為IP地址或SSH金鑰指紋已更改（通常是由於伺服器更新），而舊的仍儲存在您的known_hosts檔案中，該檔案用於SSH和SFTP連線。

如果您在連線時遇到問題，請首先確保您使用的是正確的密碼。
如果仍有問題，請按照以下說明從known_hosts檔案中刪除條目。
Mac或Linux
1.開啟終端並使用nano文字編輯器編輯以下檔案。
nano ~/.ssh/known_hosts
nano ~/.ssh/known_hosts
nano ~/.ssh/known_hosts
2.刪除所有以您的伺服器IP地址開頭的條目。
3.然後儲存文件 (Ctrl+x)。
Windows
如果您使用的是Windows，它也有一個類似的known_hosts檔案，但憑據和IP儲存在登錄檔中。
1.從開始選單啟動regedit。下面的示例使用的是Windows 10。
Windows登錄檔編輯器
2.瀏覽到以下目錄：HKEY_CURRENT_USERSoftWareSimonTathamPuTTYSshHostKeys
SSH主機金鑰
3.刪除所有以您的伺服器IP地址結尾的條目。
