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

The subnet owner called start\_call before enough blocks had passed since the subnet was registered. Compare the current block with `NetworkRegisteredAt` for the netuid plus the start-call delay and retry once the window opens.

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 NeedWaitingMoreBlocksToStarCall`.
