Add VMware vCenter host error ID 2947: Authorize Exception

Question

I'm evaluating Hyper-V/SCVMM for our shop. I've got a Hyper-V cluster running and added to SCVMM. I'm now trying to add a VMware vSphere vCenter host in order to convert some VMs,  and receive the following error with the Add VMware VirtualCenter server applet:
Virtual Machine Manager cannot complete the VirtualCenter action on the server MyVirtualCenter because of the following error: A general system error occurred: Authorize Exception.
Resolve the issue and then try the operation again.
ID: 2947
Details: Unknown error (0x194)
I haven't seen this error listed or discussed anywhere except the TechNet listing of errors.

Answer 1

[Microsoft Statement]
The error 407 is actually returned from your HTTP proxy server, we suspect it is related with proxy configuration settings.
[Our assertion]
No proxy server is configured at all – exceptions are in place just in case the SCVMM Servers take the
not selected MS Internet Explorer settings
Solution
To bypass the wrong proxy settings, we applied below solution.
In the folder where vmmservice.exe is, create a new file
vmmservice.exe.config (or add to the existing file) the following content:
<configuration>
  <system.net>
    <defaultProxy enabled="false">
    </defaultProxy>
  </system.net>
</configuration>
