Hi Crystal,

I would point you to [our docs about essentials](https://docs.portworx.com/concepts/portworx-essentials/) and the way it functions as a primer around the cause of this situation… Specifically this section:

> The Portworx Essentials license requires that your clusters be connected to the internet and send usage data to PX-Central. Portworx Essentials clusters connect with PX-Central once per hour to renew license leases. Lease periods last for 24 hours, ensuring that any temporary interruptions to your connectivity do not impact your cluster

There’s also [an FAQ in this section of the forum](https://forums.portworx.com/t/portworx-essentials-faq/346) you may wish to have a read over about, which explains more.

As for your specific case - we would need to understand if you’re a.) using this on a set of hosts that have no outbound internet connectivity (so called “air-gapped” in our docs) - in that case, you will need to provide access to a proxy that can be used to satisfy the end-point connectivity requirements for essentials. Please [search the forum](https://forums.portworx.com/search?q=essentials%20proxy) for other people’s experience with this approach as needed.

Additionally, only one Essentials cluster instance is allowed per PX-Central user, so setting up a 2nd essentials cluster for example will invalidate the first (as that’s another source of issues).
