Your tenant admin/GitHub admins must connect EZSSH to GitHub Enterprise before users are able to login to Git using EZSSH.
EZSSH Git certificates are short lived (based on your organizations settings might last between 1 and 72 hours). You will have to run this command each time the certificate is expired.
EZSSH offers the option of sending a command to your git solution to make it easier to use. Just add a -c and the command to your EZSSH git command. For Example if you want to pull you can do:
ezssh git -c "pull"
EZSSH will talk care of using your existing certificate or getting a new one and then will call git pull in another window.
