ssh_exchange_identification: Connection closed by remote host under Git bash

Question

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

Answer 1

I solved it this way.

ssh -vvv @github.com to see github IP.

Then opened browser and opened github via IP to find it was an issue with firewall.
