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

`btcli sudo start` was run before `StartCallDelay` blocks elapsed since the subnet was registered. Check readiness with `btcli sudo check-start` and wait for the remainder.

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#L334`](/code/pallets/subtensor/src/macros/errors.rs#L334).

## 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`.
