Hello, Devil_Drift_Ostr ,
A unit with this device id and type has already been created in the system.
If you have already created it in the system, try to restore access to the account where you created such a unit using the “Forgot password?” on the login page.
If you find an account with this unit, you can delete this unit and then create the same unit on you current account. – https://help.gurtam.space/en/article/configuring-and-deleting-a-unit
If this does not help, write to us at firstname.lastname@example.org, in the letter indicate which account you tried to restore.
