Unity Pro Registration Issue

Unity Pro now seems to require a clear (http, not https) connection to the internet to validate registration every time Unity loads. Unfortunately, where I work, if I can access our existing library of Unity assets, I only have https, which means I cannot even start Unity without being told I'm not registered. This is now painful, adding time to my process every time I start up Unity, and preventing me from having email and Unity running at the same time. Is this a new issue?
