这是使用 postgresql 后端的工头/木偶的新安装。尝试添加新主机（或使用我们导入的以前的数据库主机更新现有主机）时，在工头 Web ui 中会看到以下错误。
Unable to save
Create Reverse IPv4 DNS record for raul-cubito.ncct.global task failed with the following error: ERF12-2357 [ProxyAPI::ProxyException]: Unable to set DNS entry ([RestClient::BadRequest]: 400 Bad Request) for proxy https://factory-7.ncct.global:8443/dns
我们还在命名日志中收到以下错误（raul-cubito.ncct.global 是创建的随机名称工头）。
