嘗試從 Unisphere 取得技術諮詢時，產生下列錯誤訊息：
There was an error when retrieving catalog from Dell EMC through configured proxy (Error Code:0x6400bda)'
EMCSystemLogFile.log shows the following:

Causa
在這種情況下，客戶無法直接存取 DNS 伺服器，只能使用代理伺服器退出。 造成此問題的原因是，在 Unity 與代理伺服器之間的資料傳輸完成之前，colu.emc.com 和代理伺服器間的連線便已關閉。 這似乎是由於 curl 處理連線的方式所造成。
Risoluzione
修正
此問題的修正將會包含在未來的 Dell EMC Unity OE 版本中。 請觀看此知識文章以瞭解更新。
因應措施
請勿使用代理伺服器擷取技術諮詢，或設定暫時跳過 Unisphere，直到推出修正此問題的代碼為止。

Informazioni aggiuntive
在將「代理伺服器 URL」新增至 curl 命令時，成功並傳回：
