# HotKeyNotRegisteredInNetwork (/docs/errors/chain/HotKeyNotRegisteredInNetwork)

The hotkey is not registered on the relevant subnet, raised by `serve_axon`/`serve_prometheus` for the serving netuid or by identity calls requiring registration on any subnet. Verify registration with `btcli query uid --netuid <n>` (or `btcli query netuids-for-hotkey`) and register via `btcli subnets register` first.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`not_registered`](/docs/errors/not-registered).

## Remediation [#remediation]

Register the hotkey on this subnet first with `btcli subnets register`

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