I have recently upgraded from VS2012 RC to RTM, and since the upgrade to RTM, I can no longer access nuget. I receive the following error in the Manage NuGet Packages window.
The ServicePointManager does not support proxies with the https scheme.
I looked at the solution offered here in a previous stack overflow question, but it does not apply to me as I am not behind a firewall (certainly not supposed to be and verified by http://whatismyipaddress.com/proxy-check). I can also see the RSS feeds / VS can access other network resources, which in the previous question the problem was related to all VS internet traffic not just NuGet as it is in my case.
Any ideas what could have caused this, or how to restore access to NuGet? I have tried this on my machines at work, and my personal computer at home, all with the same effect.
The solution is in this answer:
The problem is related to a bad SSL cert on the default Nuget package source.
