Hi. I can not start local harvesting getting :ERROR 401
This operation cannot be completed because it might leak a private key by sending it to a remote NIS.


And I can not delegated harvesting getting: ERROR 306
An error occurred that the development team did not have foreseen. Apologies for this, maybe a retry might help. Otherwise, please open up an issue within the NEM NIS/NCC community.

any ideas please?
