The visual studio stopped sending my commits to the bitbucket and this error appears
Error encountered while cloning the remote repository: Git faile
I had the same issue, I found an answer that worked for me here: https://github.com/github/VisualStudio/issues/949
Below are the steps mentioned to fix: It seems that the bundled Git-Credential-Manager-for-Windows/ in VIsual Studio 2017 is not the latest release. Downloading the latest release and putting it on top of the files in Visual Studio 2017 worked for me.
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\Git\mingw32\libexec\ (or wherever your 'missing' git-askpass.exe resides).
