Hi,
When checking for updates via VAMI on VUM 3.4, I get this error:
Failed to check for updates(Error downloading manifest. Please contact your vendor. The requested URL returned error: 404 URL: https://vapp-updates.vmware.com/vai-catalog/valm/vmw/4f0e208a-2e0a-4b20-8453-7460ab3e8286/3.4.0.0.la...) on Thursday, February 11, 2016 1:04:41 AM GMT+01:00
Known issue perhaps?
I am running 3.4.0.0 Build 2933395, which should be the latest version.
