There was an error when retrieving catalog from Dell EMC through configured proxy (Error Code:0x6400bda)'
EMCSystemLogFile.log shows the following:

CURL-kommandot för att kontrollera anslutning till proxy-servern fungerar inte:

Causa
I det här fallet tillåter kunden inte direkt åtkomst till en DNS-server och använder endast proxyservern för att komma ut. Orsaken till det här problemet är att anslutningen mellan colu.emc.com och proxyservern stängdes innan dataöverföringen mellan Unity och proxyservern slutfördes. Detta verkar bero på hur way curl hanterar anslutningarna.
Risoluzione
Åtgärd
Problemet åtgärdas i en framtida Dell EMC Unity OE-version. Läs den här artikeln i Kunskapsbanken om du vill ha uppdateringar.
Tillfällig lösning
Använd inte proxyservern för hämtning av teknisk rådgivning eller konfigurera en tillfällig förbikoppling för Unisphere tills koden som åtgärdar problemet har släppts.
