BeneficiaryDoesNotOwnHotkey

Sign with the key or origin that owns the target object, then retry

When ending a subnet lease, the hotkey passed for the ownership handover is not owned by the lease's beneficiary coldkey. Check the Owner storage for that hotkey and pass a hotkey the beneficiary coldkey actually owns.

Declared by the SubtensorModule pallet; it classifies to the semantic code not_authorized.
