What port is NuGet using when loading a package through Visual Studio

Question

I am using VS 2010 (package manager console) to download NuGet packages (2.5.40416.9020/Latest). It uses the URL https://nuget.org/api/v2/ . This gives me an error as shown below.

Install-Package : An error occurred while loading packages from'https://nuget.org/api/v2/': The remote name could not be resolved: 'nuget.org' At line:1 char:16 + Install-Package <<<< Rx-Main + CategoryInfo : NotSpecified: (:) [Install-Package], InvalidOperationException + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand 

But when I access the same URL through a browser, I can browse the site. I am on a corporate network, so a firewall can block the port (except for 80 and 443).

So, which port does NuGet use when downloading packages through the Package Manager Console (VS 2010)?

Answer 1

https://nuget.org/api/v2/ means port 443 (standard port for HTTPS)

If you work on a corporate network, port 80 and 443 are usually redirected through a proxy server.

Most likely, for some reason, NuGet is not using your proxy settings, so it cannot find the proxy server and is stopped by the corporate firewall.

Go to Program Files \ Microsoft Visual Studio 14.0 \ Common7 \ IDE \ devenv.exe.config

 Set ipv6 enabled from true to false

  <system.net> <settings> <ipv6 enabled="false"/> </settings> </system.net> 

Answer 3

I was not able to download the nugget package through the console, it threw an error, for example:

"Unable to connect remote server"

I followed the steps below and set ipv6 from true to false. This solved my problem.

 C:\Program Files\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe.config <system.net> <settings> <ipv6 enabled="false"/> </settings> </system.net>
