无法通过SSH连接到Ansible

Question

我创建具有以下内容的主机文件

[web]
167.172.xxx.xxx

我在Web服务器上有一个用户root，并且公共密钥也已添加到authorized_keys文件中。

[运行命令ansible web -m ping -i hosts时出现以下错误

167.172.xxx.xxx | UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to connect to the host via ssh: ssh: connect to host 167.172.xxx.xxx port 22: Operation timed out",
    "unreachable": true
}

我尝试过hosts文件的其他变体，下面是我尝试过的另一种也不起作用的方法

[web]
167.172.xxx.xxx ansible_connection=ssh ansible_user=user ansible_ssh_private_key_file=~/.ssh/id_rsa.pub

但是，我可以使用ssh [email protected]毫无疑问地进入服务器，我是Ansible的新手，但这应该不会花24个小时，请帮助，我被困住了。

与-vvv一起运行

看起来比ssh身份验证问题更多的是网络问题。您的网络中是否存在用于连接到该服务器的代理？如果是，则需要在命令中传递代理详细信息。
