I was experiencing the same error in VS 2010. However, the accepted answer by Rick Liddle wasn't working for me. The strange thing is that I could get a list of available packages from the Package Manager Console no problem, so it still wasn't a connectivity issue.

Had this issue today. My list wasn't empty, but it only had 6 pages and nothing I needed was available.
The flag in the top right corner showed there was an updated to the NPM. Updating via that didn't restore the missing packages.
There was an update to Nuget yesterday (2014-04-02).
Try adding a new package source from that window and set the source to http://packages.nuget.org/v1/FeedService.svc
I had similar issue with VS2015. The default package feed (https://www.nuget.org/api/v2/curated-feeds/microsoftdotnet/) returned no results. Switched to https://www.nuget.org/api/v2 and was able to find packages again.
Tools->Options->Nuget Package Manager->Package Sources and add new Package Source.
