Hetzner错误:拒绝权限(公开密钥)

Question

我正试图在hetzner部署上从github获得rails get的回购！但是在ssh中显示了这个结果！

自从更改/etc/ssh/sshd_ PasswordAuthentication _config后，我已经尝试了一切

在known_hosts上添加keygen，authorized_keys在服务器和github上添加keygen

创建一个ed25519 keygen并尝试它

一切都是静止的

github给我git@github.com:拒绝许可

PreferredAuthentications publickey

在hetzner专用服务器中，您需要首先检查的是：

ssh -Tv git@github.com

只要您没有看到“欢迎”消息，任何其他进程(假设它是使用该服务器上的同一个用户帐户执行的)都无法使用SSH从GitHub中获取。
