I use shell "git push origin master" on AWS server today,  and return errror :

ssh: connect to host bitbucket.org port 22: Connection refused
fatal: The remote end hung up unexpectedly

It's running in yestoday.

Hi! One possibility is a firewall configuration issue. Did any firewall configuration changes happen since yesterday to cause port 22 to be closed for outbound connections? If not, another  possibility is an authentication failure. Check to see if the ssh public key configured on your AWS server (where you are running the git push) matches a ssh public key registered to an account with access to the repository.
