web config - Visual Studio 2010 nuget error: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel

Question

Whenever I'm trying to install something or even just list the packages I get this error "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel"

I tried this solution from Codeplex with no luck.

I use the latest version of Nuget.

I also tried different options in devenv.exe.config like this:

<servicePointManager  checkCertificateName="false"    checkCertificateRevocationList="false"/>

Answer 1

• Go to VS2010 → Tools → Library Package Manager → Package Manager Settings.

• Choose Package Manager → Package Sources.

• Add a new package source as:

  • Name: NugetSource

  • Source: http://packages.nuget.org/v1/FeedService.svc/

• Move Up the newly added package source to first position.

• UnCheck existing "Nuget official package source"

• Restart VS2010.
