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.

Remediation

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

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