# StartCallNotReady (/docs/errors/chain/StartCallNotReady)

`start_call` was made before `StartCallDelay` blocks elapsed since the subnet was registered. Compare the current block against `NetworkRegisteredAt` for the netuid plus `StartCallDelay`, and wait for the remainder.

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 StartCallNotReady`.
