Activation failed. Error code: server error (-2). Check and try again.

Keep getting this error, and I still can't activate my rc2 controller for dji mini 4 pro
Is there any solution for this issue?

Hi there, thank you for bringing this to our attention and we sincerely apologize for any inconvenience you may have experienced.

After our investigation, it seems the activation failure might be due to a device firmware issue. Before we proceed, may we confirm if you're in New Zealand currently and also provide us with the SN of your device for further checking? Could you please tell us if you purchased it from the dealer? If so, we recommend that you seek assistance from the dealer.

If you need further assistance during the process, please don't hesitate to contact us. Thanks for your cooperation.
