You may be required to reauthenticate your ERP system connection. This issue can occur for a few reasons:

- Your authentication token has expired and failed to automatically refresh.
- The user account initially used for authentication is no longer active within your organization (e.g., the user has left or their credentials were disabled).

Follow these steps to reauthenticate.
