# E1615 — Runner deregister in dispute cooldown until block

| Property | Value |
| - | - |
| **Code** | `1615` |
| **Slug** | `E1615` |
| **Category** | `runner` (Runner / Consensus) |
| **CIP** | CIP-9 §5.1.1 |

## What happened

Runner deregister in dispute cooldown until block \{until}.

This is the receipt's `what` text, produced by the node's `ExecutionError::RunnerDisputeCooldown`. Placeholders in braces are filled from the failing transaction.

## Why it happened

The node rejected the operation with `E1615` (category `runner`, Runner / Consensus). The receipt's `why` field carries the specific cause and `context` carries structured details, such as the values that filled the placeholders above.

The normative rule is in CIP-9 §5.1.1.

## How to fix

The dispute window after the runner's last settlement event has not elapsed yet. Retry after the indicated block height.
