在 sshj 中处理“[HOST_KEY_NOT_VERIFIABLE] 无法用指纹验证 'ssh-rsa' 主机密钥”

我在sshj上有一个奇怪的问题（我使用的是sshj v0.6.0），为此我需要某人的帮助。使用公钥进行身份验证在某些计算机上工作正常，但在其他计算机上无法正常工作，我看到以下错误。

我能分辨出的唯一区别是，有问题的 UNIX ID 即 coonradt 似乎仅在触发以下错误的框中具有 ~/.ssh/config 下列出的配置设置

Host *
    Protocol 1,2
    FallBackToRsh no
    ForwardAgent yes
    ForwardX11 yes
    PasswordAuthentication yes
    RhostsAuthentication no
    RhostsRSAAuthentication no
    RSAAuthentication yes
    NoHostAuthenticationForLocalhost yes
    StrictHostKeyChecking no
  KeepAlive yes

从上面的配置文件中，我了解到有问题的ID应该使用协议1，2，我怀疑这可能与我的失败有关（我不是很确定，但这只是一种预感）

对于所有其他可以正常工作的UNIX ID，我没有任何这样的配置文件。

PS ：我无法更改UNIX ID“coonradt”的配置，因为此ID正由中央哈德逊服务器使用。

如果有人能帮我建议这里可能出了什么问题，将不胜感激

以下是我看到的错误：
