# Invalid Subscription

> This error occurs when a user’s vehicle is compatible but their connected services subscription is inactive because either it has expired or it has never been activated.

Smartcar will direct the user to the connected services website to (re-)activate their subscription. However, a user may choose to return back to your application instead, like in the example below.

In the event of an `AUTHENTICATION_FAILED`, the user will need to be prompted to re-connect their vehicle. Smartcar Connect Re-authentication makes the process of re-authenticating a user much more seamless. In addition, the `AUTHENTICATION_FAILED` error provides a partially constructed URL for the re-authentication flow inside the resolution object.
