There are several scenarios where a VNC offline license file becomes necessary:

An (typically a .vnc or .txt file containing a cryptographic key string) serves as a digital certificate. It tells the local VNC Server instance that the deployment is legitimate without needing to check in with RealVNC’s cloud servers. Subscription Types and Eligibility
