If a Dollar Universe license is less than one month from its expiry date, the Information column for the node will display the following message: "The license is going to expire". This message is normal and is meant to be a warning about the impending license expiration.By default, when a new node is installed there is a one month grace period where the node will be fully functional, but it will still display the "license is going to expire" notice even when no license is present.
If the license had expired, the information column would display the following message: "The license is expired" and the node would have stopped and logged an entry in the universe.log file indicating the license had expired and the node had stopped.
