• try to turn off firewall, any anti-virus software

3) close VS, delete C:\Users\xxx(current user name)\AppData\Roaming\NuGet\NuGet.Config file, and then restart VS to regenerate the global nuget.config file.

4) or you could try to use this path http://packages.nuget.org/v1/FeedService.svc/ as nuget.org .
