Google Cloud Platform VM 无法从本地 SSH（权限被拒绝（公钥））

Question

我尝试从我的 MacBook 终端 ssh 到 Google Cloud VM，昨天运行良好。 根据我的理解，我有我的公钥和私钥。

当我尝试如下连接时，

XXXXXXXX-MacBook-Pro:~ xxxxxxxx$ ssh -i .ssh/id_rsa xxxxxxxx@12.345.678.910 -v

错误调试如下。 （用户名、IP 地址等被屏蔽）

“服务器主机密钥”和“提供公钥：.ssh/id_rsa RSA”不同。 但是，我从本地复制 & pasteed.ssh/id_rsa.pub 并且 Google Cloud VM 中的 authorized_keys 附加了相同的公钥。

是什么原因造成的，我该如何解决？
