# NeedWaitingMoreBlocksToStarCall (/docs/errors/chain/NeedWaitingMoreBlocksToStarCall)

The subnet owner ran `btcli sudo start` before enough blocks had passed since the subnet was registered. Check readiness with `btcli sudo check-start` and retry once the window opens.

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

Declared at [`pallets/subtensor/src/macros/errors.rs#L203`](/code/pallets/subtensor/src/macros/errors.rs#L203).

## Remediation [#remediation]

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

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