我在连接到我的 ssh 主机时遇到问题。我一直以详细模式收到此消息：

Are you sure you want to continue connecting (yes/no)?
Host key verification failed.
仅供参考：在粘贴的跟踪中，我替换了用户名、主机和 ip……以防万一有人感到困惑。
这是我的 ssh_config：

我读了很多关于主机密钥自上次登录以来可能已更改的信息。因此，我已经尝试删除 known_hosts 文件中的条目，但无论使用什么 ssh 服务器，我仍然会收到该错误。
知道我在这里可能做错了什么吗？
更多信息：我最近将 mac os 更新为 sierra。也许它是相关的。
