Error when trying to install nuget package

I was able to figure it out using wireshark. Not sure why i was wasn't able to see the traffic with fiddler (with https proxy setup for all proceses) but anyways it was trying to download the package from: https://nugetgallery.blob.core.windows.net/packages/Modernizr.2.5.3.nupkg

which was being blocked by websense. Admin opened it up and now everything is working. I'm assuming the URL for some packages are different (like dapper) which was able to download successfully.
