Git clone from TFS error: RPC failed; result=22, HTTP code = 401

I'm currently trying to clone a repository from TFS on my Mac but got below error:

$ git clone https://tfs.xx.com/yy/_git/Mobile
Cloning into 'Mobile'...
Username for 'https://tfs.xx.com': xxx
Password for 'https://[email protected]': 
error: RPC failed; result=22, HTTP code = 401
fatal: The remote end hung up unexpectedly

Environment:

Googled several possible solutions but all failed.

  1. increase http post buffer

    git config --global http.postBuffer 524288000

  2. cache credentials in the secure keychain

    git config --global credential.helper osxkeychain

  3. upgrade git to the latest version v2.6.4 (uninstalled after failed)

I suspect that the root case might be the authentication config on the TFS server. TFS server block access which is not based on NTLM of window. Saying so, my evidence is that when I run git with GIT_CURL_VERBOSE=1. It showed more details and at the end of the log. There's message:

* NTLM handshake rejected
* Authentication problem. Ignoring this.

A part of detail log on Mac:

$ GIT_CURL_VERBOSE=1 git clone https://tfs.xx.com/yy/_git/Mobile

Well, when I called same command on Windows. It executed correctly. The difference is that windows showed: 

* NTLM auth restarted

and continued. While Mac responded:

* NTLM handshake rejected
* Authentication problem. Ignoring this

and then stopped.

Some time this problem occur due to slow network speed.Try to clone repository on a better network speed.
