Error downloading Virtual Machine config file

This is always an environmental issue - i.e with vCenter, your network or configuration settings on the server where the VSA is installed. Sometimes having an internet proxy server on your access node or configured via group policy prevents HTTPS connections to vCenter.

When trying to access vCenter you are getting a 401 error.

Try check for local proxy servers preventing HTTPS connections:

netsh winhttp show proxy

Try to remove proxy settings:

netsh winhttp reset proxy
