Conjure-up with firewall

I will open this issue at AskUbuntu if this is the wrong place.
I have MASS working in an environment where there is an HTTP . MAAS is on a private internal network.

When I use conjure-up I have a lot of difficulties.
I set the enviroment variables http_rpoxy https_proxy and no_proxy for the internal MAAS server.
But it seems to freeze up, I am not sure at what part.
I think the proxy settings are not being used properly.
I am now tring with conjure-up --http_proxy etc.

I am asking if anyone else has conjure-up working behind a corporate proxy. Thankyou!
