In order to generate daily rewards, Nodes must be online for at least 6 hours each day, either locally or via a VPS service.
It's easy to see if your nodes are online:
Sign in to connectunited.com.

Your nodes' online status will be displayed as in the below image. Here you can view your total node licenses, and how many nodes from each brand are currently running.
