[Question]使用密钥方式无法连接到主机

[dakangsiji]

请描述您的问题.
ko凭据为私钥，节点authorized_keys 已写入公钥信息，但是ko上始终无法连接：

{"bj-at1":"{"action":"setup","changed":false,"msg":"Failed to connect to the host via ssh: Warning: Permanently added '172.16.1.196' (ECDSA) to the list of known hosts.r Authorized users only. All activities may be monitored and reported. Load key "/var/kobe/data/key/bj-at1-9d76ce2b-ee41-40e9-a335-b76737657570.pem": invalid formatr root@172.16.1.196: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).","unreachable":true}"}

其他节点上用此公私钥完全没有问题，抓包也未看见出异常；

本人添加主机时也遇到初始化失败问题，部署机和要添加的主机之间本身是互通的，各自的ssh连接也都正常，ssh端口为默认22端口，IP地址也填写的同一局域网内的IP，所有防火墙均已关闭，不管是采用密码模式还是密钥均连接失败，这种情况需要如何解决，谢谢！

部署版本kubeoperator-release-v3.16.4-amd64.tar.gz，失败的提示信息如下：
{"dev01":"{"action":"setup","changed":false,"msg":"Failed to connect to the host via ssh: ssh: connect to host xxx.xxx.xxx.xxx port 22: Operation timed out","unreachable":true}"}
