Sintomi
尝试从 Unisphere 检索技术公告时，会生成以下错误消息：
There was an error when retrieving catalog from Dell EMC through configured proxy (Error Code:0x6400bda)'
EMCSystemLogFile.log 显示以下内容：
2021-01-28T17:09:09.974Z" "xxx_spb@APM00123456789" "Neo_CEM" "17037" "local/admin" "WARN" "14:380012" :: "Failed to get technical advisory with configured proxy http://proxy.FQDN.com:8080." :: Category=User Component=EmcSupportServices TimeZone=UTC
用于检查与代理服务器的连接的 curl 命令失败：
# curl -X POST https://colu.emc.com:443/soap/rpc -H "Content-Type: text/xml;charset=UTF-8" -H "SOAPAction:" -v
Hostname was NOT found in DNS cache
Could not resolve host: colu.emc.com
Closing connection 0
curl: (6) Could not resolve host: colu.emc.com
将代理服务器添加到 curl 命令的操作成功。
# curl -x "http://<proxy.server.url>.com:8080" -X POST https://colu.emc.com:443/soap/rpc -H "Content-Type: text/xml;charset=UTF-8" -H "SOAPAction:"-v

Causa
在这种情况下，客户不允许直接访问 DNS 服务器，只能使用代理服务器来退出。 出现此问题的原因是：在 Unity 与代理服务器之间的数据传输完成之前，colu.emc.com 与代理服务器之间的连接已关闭。 这似乎是由于 curl 处理连接的方式造成的。
Risoluzione
修复
此问题的修复将包含在未来的 Dell EMC Unity OE 版本中。 请查看此知识库文章以了解更新内容。
解决办法
在发布可修复此问题的代码之前，请勿使用代理服务器检索技术公告或为 Unisphere 设置临时旁路来绕过问题。

Informazioni aggiuntive
将“代理服务器 URL”添加到 curl 命令时，它会成功：
