How to solve SSL issue while cloning the GIT
You can trun off the SSL using
git config --global http.sslVerify false
$ git -c http.sslVerify=false clone https://192.10.10.21/Git.Server/project.git
and provide the 192.10.10.21 's user name and password.
Why this is occurring ?
While we install Git, we might selected, "Use the OpenSSL Library" instead, we should choose, "Use the native windows secure channel."
