无法通过SSH连接到服务器

Question

我正在尝试使用SSH连接到AWS服务器。但由于某种原因，我不能。当我跑到下面时：
ssh -i <keypair.pem> ec2-user@<ip> -vvv

我明白了：
OpenSSH_7.6p1 Ubuntu-4, OpenSSL 1.0.2n 7 Dec 2017 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug2: resolving "<ip>" port 22 debug2: ssh_connect_direct: needpriv 0 debug1: Connecting to <ip> [<ip>] port 22. debug1: Connection established. debug1: key_load_public: No such file or directory debug1: identity file <keypair.pem> type -1 debug1: key_load_public: No such file or directory debug1: identity file <keypair.pem>-cert type -1 debug1: Local version string SSH-2.0-OpenSSH_7.6p1 Ubuntu-4

我猜这是路由器ip禁止配置问题？我该怎么办？

检查远程.ssh目录的权限和内容。在authorized_keys文件中有你的公钥吗？请参阅以下链接
