If you are a Shared Hosting client, you can use an FTP client in order to update your website content. Please use the following configuration settings.
Server name: s1.cloud.stottsan.net
Username: your primary account username
Password: your primary account password
Note that if you have multiple websites hosted under the same account, you will need to use a different directory path in order to update the non-primary site. If you want to update the another.com website, for example, you would use domains/shotnight.com/public_html.
