Start with the provided docker-compose configuration and the hbbs/hbbr container logs, then inspect how the RustDesk server image handles the hbbs and hbbr commands and the reported licensing error. Confirm whether the compose setup is supported as shown and document the required configuration or expected behavior; done means the containers start without repeating this error.
