In MS Visual studio, I'm trying to install Nuget packages into my solution.
When I choose the option "Manage Nuget Packages for Solution" and attempt to install a package, I get the message "Unable to connect to the remote server".
I do have Internet connection so do not understand why I always get this message.
Is anyone aware of some steps that can be taken to rectify this issue?
Thanks
Clearing HTTP_PROXY worked for me.
Let me fix it myself

Solved. that's because Visual studio is using fiddler http connection.
all you have to do is to open fiddler=> fiddler option => connection => uncheck "act as system proxy on startup".
thats all!
This started happening to me quite randomly today on Visual Studio 2012. A bit simplistic but, after checking if the Nuget site itself was up and trying the Package Manager Console, my solution was to:
Close and reopen Visual Studio
Suddenly it could connect to the Nuget server again and download my much needed packages.
Tools -> Library Package Manager -> Package Manager Settings -> Clear Package Cache
That worked for me
Clearing the Proxy Cache in IE Fixed this for me. Use these two command lines in the command prompt (run as administrator)
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 0 /f then
reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /f The details can be found at https://support.microsoft.com/en-us/kb/2289942
I solved it on mine by commenting out the
section from the devenv.exe.config located at
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe.config Here's how I fixed this issue after none of the suggestions above worked:
Internet Explorer > Tools > Connections > Lan Settings
Uncheck 'Automatically Detect Settings' box. This solved the Nuget Package Manager issue for me. Additionally it fixed another connectivity problem I was having with a VMWare virtual desktop AND... it greatly increased speed in Internet Explorer when trying to connect to secure sites.
I had this issue with VS 2010 package restore even after updating the Nuget Package Manager to the latest and also unselecting all package sources I could. I was getting an error while enabling the Nuget Package Restore option on the solution.
I resolved this by using a different box that didn't have restricted https access to the nuget server. When I used VS 2012 from a different box to enable package restore, it worked fine. I believe it needs to be able to connect to the nuget online server to download the latest nuget.exe used during restore operations. So one option you can use is to perform the Enable Package Restore process from a server that has all the internet access necessary, and then check-in the changes. Once these changes are checked-in, you can then load the solution again from VS 2010 or VS 2012 and use the nuget restore capabilities.
Hope that helps!
I had the same symptoms, and apparently visual studio was using some proxy setting set up in IE. It turned out that my problem was one of the following:
After completing the update wizard, and clearing all proxy settings, my NuGet package manager was working again.
Had the same issue, it was solution specific, and none of the above worked. I deleted the visual studio solution user options file (.suo) and restarted VS 2013 and now I can update and install packages again.
Finally resolved. I disabled an extension in Chrome. I had installed it to hide my real location.
