This likely means you already had a trial license with the email you’ve provided, and your trial has expired. You can either use a new email, or you can reach out to be via email at cbowden@influxdata.com with the relevant email so I can remove your trial license from the server so you can try again with a new one. Alternatively, it means you don’t have a license file on your system, and the system isn’t connected to the internet in a way that allows it to establish a connection with our license servers and request a new trial license.
