问题
I have recently upgraded to VS 2015 (Update 3) on the client side and TFS 2015 (Update 3) on server side. The Git operations worked for a while, then I started getting following error when trying to clone a git repo:
Error encountered while cloning the remote repository: An error occurred while sending the request.
Inner Exception:
The remote server returned an error: (401) Unauthorized.
Inner Exception:
No credentials are available in the security package
But I can navigate to repo in the browser without any problems. Then, I figured this may due my client side settings. I tried removing the VS cache as well as TFS cache. Nothing worked. When I used Fiddler, it should following information:
It revealed following information:

With this information, I searched for libgit2*.* file in my visual studio folders. I found several instances of LibGit2Sharp.dll. All of them have same version (0.22.0.0) but one instance had the version 14.0.25029.0. I tried copy the version 0.22.0.0 over on top of 14.0.25029.0. But visual studio complained about it during launch. The folder with 14.* version is found in "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions" folder and it contains several dlls that start with "Microsoft.TeamFoundation.". All of those dlls have the version: 14.102.25521.0 (which is what I found in the fiddler trace).
Looks like I am at the right problem area but not sure how to fix the error.
Any ideas?

After struggling with the above problem for a week, I posted the question today. But right after posting, I landed on a solution.
It has nothing to do with visual studio/tfs upgrade. I must have entered wrong tfs credential information (while checking remember me box). With remember me feature, the team explorer never gave me a chance to correct the credential information and probably kept using stored wrong credentials. Here is what I had to do to correct the issue:
- Control Panel\User Accounts\Credential Manager
- Remove any tfs related credentials.
- Launch visual studio
- It will now prompt you for tfs credential information.
Problem solved.
The following post (though dated) helped me in solving the problem: https://blogs.msdn.microsoft.com/visualstudioalm/2012/08/29/clearing-the-credentials-for-connecting-to-a-team-foundation-server/
