木偶:没有收到证书

我在更新版本(6)的puppet上有一个最低限度的默认puppet主/从配置,我正试图在virtualbox VMs中为一个原型初始化它。但是,代理似乎无法正确连接到主服务器。

在我的硕士学位上,我只有两个证书,所以很明显,申请通过了:

 "localhost" (SHA256) 1C:E7:D0:FF:35:A3:5B:CA:37:02:13:CC:75:20:B5:54:42:BA:AA:C9:61:9D:02:22:B3:28:E3:C3:4D:FE:5F:CC
  "slave1"    (SHA256) 35:A8:C5:E8:8A:1D:58:F6:DA:EC:8A:4D:9F:30:53:3E:F8:A1:01:27:F4:D7:62:5F:82:1C:E0:6B:37:82:A8:A2

Nothing to do
waiting to run puppet....

如何确定为什么会发生这些404错误?
