I work at win7 and set up git server with sshd. I git --bare init myapp.git, and clone ssh://git@localhost/home/git/myapp.git in Cywgin
git --bare init myapp.git
ssh://git@localhost/home/git/myapp.git
For me, the issue was that there was a proxy set in /etc/ssh/ssh_config and it was down, solved the issue by whitelisting the remote git IP and removing the proxy line.
Hope this helps someone.
