If you are using an incorrect or expired license key, Tamr will give you a "Tamr license is not valid" error when trying to sign in. To obtain a new license key, reach out to Tamr Support.
Ensure that you are using the correct license key given to your organization, as you might be using the default license key that comes with the AMI but expires after the first month.
To update the license key, follow the instructions found here.
