检查 DNS 服务器是否已配置。运行以下命令：

cat /etc/resolv.conf

使用上面输出中列出的第一个“名称服务器”的 IP 运行以下命令：

ping <nameserver IP>

curl -kv <nameserver IP>:53

检查 ACM 是否可以将 DPC IP 地址解析为主机名：

host -W 10 -T <DPC IP>

Where <DPC IP> is the IP of the DPC server.

Cause

host 命令不会返回 DPC IP 地址的正确 FQDN。这表明来自客户环境（其外部 DNS）的主机名解析存在问题，这就是 REST 调用失败的原因。

Resolution

IDPA 系统需要通过 DNS 进行名称解析。
如果 DNS 解析失败，请让客户网络团队解决此问题。
解决 DNS 问题后，ACM 可以连接到 DPC，此问题已解决。
