Causa
In dit geval staat de klant geen directe toegang tot een DNS-server toe en gebruikt hij alleen een proxyserver om eruit te komen. De oorzaak van dit probleem is dat de verbinding tussen colu.emc.com en de proxyserver is verbroken voordat de dataoverdracht tussen Unity en de proxyserver werd voltooid. Dit is te wijten aan de manier waarop curl met de verbindingen omgaat.
Risoluzione
Oplossing
De oplossing voor dit probleem zal worden opgenomen in een toekomstige Dell EMC Unity OE-release. Zie dit Knowledge Base-artikel voor updates.
Tijdelijke oplossing
Gebruik de proxyserver niet voor het ophalen van technische adviezen of stel een tijdelijke omleiding in voor Unisphere totdat de programmatuur waarmee dit probleem wordt opgelost wordt vrijgegeven.
