SSH 無法連接到 Google Cloud Compute-Engine-Instance：權限被拒絕（公鑰）
我按照本教程介紹瞭如何使用 ssh 設置 GCE-VM。但是，我似乎無法像影片中的那個人那樣通過 ssh 成功連接！這是我嘗試連接時的輸出（IP 是虛構的）：

- 在不同的區域（亞洲而不是歐洲）設置 VM
- 使用不同的映像設置 VM（debian、ubuntu、minimal 和 standard）
- 在 Windows 和 Linux 下嘗試設置
enable-oslogin = TRUE項目範圍和特定實例- 從公共 ssh-key 中刪除主機部分
ssh [IP],ssh [USER_IN_KEY]@[IP],ssh [USER_ON_VM]@[IP]我真的不知道在哪裡尋找問題了！誰能給我一個關於我可以嘗試什麼或問題可能出在哪裡的指針或建議？
謝謝！
我嘗試在新的 VM 實例中重現我自己的項目中的錯誤，並按照您提到的影片，我收到了與您收到的相同的錯誤：
ssh <MY-IP> The authenticity of host '<MY-IP> (<MY-IP>)' can't be established. ECDSA key fingerprint is SHA256:A.... Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '<MY-IP>' (ECDSA) to the list of known hosts. <MY-USER>@<MY-IP>: Permission denied (publickey).我按照以下步驟操作：改為使用第三方工具連接，我能夠使用 ssh 將我的 Debian 連接到我的新實例：
ssh -i <my-private-ssh-key> <MY-IP>Linux <MY-INSTANCE-NAME> 4.19.0-11-cloud-amd64 #1 SMP Debian 4.19.146-1 (2020-09-17) x86_64 The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright.

Last login: Thu Oct 1 14:50:16 2020 from <SOME-IP> <MY-USER>s@<MY-INSTANCE-NAME>:~$ hostname <MY-INSTANCE-NAME>另一個不錯的選擇是安裝 Google Cloud SDK，然後使用
gcloud compute ssh --project <PROJECT_ID> --zone <ZONE> <VM-INSTANCE_NAME>您可以查看以下連結以獲取更多資訊。
