# LeaseHasNotEnded (/docs/errors/chain/LeaseHasNotEnded)

The lease termination was attempted before the lease's `end_block` was reached. Compare the current block height with the `end_block` stored in `SubnetLeases` for the lease id and retry after it passes.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`too_early`](/docs/errors/too-early).

## Remediation [#remediation]

The required window has not opened yet; wait some blocks and retry

The same explanation is available in the terminal: `btcli explain LeaseHasNotEnded`.
