Can not use embedded git

[amber]

I was using tortoiseGit and moved to SourceTree

When I Tried to clone source code and I got the message

Command: git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks ls-remote http://10.10.1.154:7990/scm/ccisw/cci-sw-public.git

출력:
오류: fatal: Authentication failed for 'http://10.10.1.154:7990/scm/ccisw/cci-sw-public.git/'

On the web, I found I need to use embedded git and update embedded git.

When I tried to use embedded git using 

tool=> option=> Git => Gitversion => Embedded, I get message

Unable to extract: Can not create SSL/TLS security channel

What can I do next?

I still can clone from TortoiseGit from same git address
