The Jira connector is fairly standard. It asks for your username, password and URL. Your URL will be something like: https://starfishetl.atlassian.net. Your "password" may not be your password. In some, or all, accounts, you must supply an API key as your password. To generate an API key, as of this writing, open the "Settings" gear icon -> Atlassian Account Settings -> Security -> Create and manage API tokens. Create a Token for Starfish to use and put that into the "password" field.
