what type of proxy is that, and how did it's admin set up the access to the proxy for HTTPS?

Usually, for non-transperent proxies, some dedicated proxy port is configured and needs to be used by the clients (and hence configured in your proxy URL) - i.e. Squid typically uses 3128, so you'd have to specify "HTTPS_PROXY=http://your.proxy.machine.name.com:3128". But there are many different port numbering approaches, so see your proxy admin for details.

It might also be a case where in the proxy, using the "CONNECT" method isn't allowed or needs client authentication to the proxy. Again, ask your proxy admin for the specifics of your proxy's setup.
