解決方法

According to this

Sometimes, firewalls refuse to allow SSH connections entirely. If using HTTPS cloning with credential caching is not an option, you can attempt to clone using an SSH connection made over the HTTPS port. Most firewall rules should allow this, but proxy servers may interfere

➜  ~ nano ~/.ssh/config
Host github.com
 Hostname ssh.github.com
 Port 443
➜  ~ ssh -T git@github.com
