Have vCenter 6 Appliance and when setting up a content library, I am using "Subscribed content library" and "Download content immediately" I receive yellow banner at top stating "Invalid URL. HTTP request error: Connection refused."
URL is: https://s3-us-west-1.amazonaws.com/vghetto-content-library/lib.json
Our internet use a proxy server. I have proxies setup through the web browser and I can get to the URL if I place directly in the browser, so seems valid.
