Using git when ssh has been blocked

Network admins sometimes block port 22 for ‘security’ purposes. If you have configured your git remotes to use ssh, this also prevents you from pulling or pushing changes.

A quick workaround (source) is to add the following to your ~/.ssh/config

Host github.com
    Hostname ssh.github.com
    Port 443
Host gitlab.com
    Hostname altssh.gitlab.com
    Port 443
Host bitbucket.org
    Hostname altssh.bitbucket.org
    Port 443

Of course, the above won’t help you if you are using a different git host, but it’s better than nothing.
