Kinda vague, is there any other message with it? Could be still working on your documents, an issue with your car, maybe you have been deactivated, maybe your in an area your not allowed to drive. Greenlight hub is your best bet.
Do you have connectivity? I get that message when I am in a dead zone. Chances are you are just in a waiting period. When did you get your vehicle inspection submitted? When did you finish uploading your documentation? Are you a US citizen? That sometimes takes longer for verification I have been told.
