Unable to Authenticate Telsa Power wall (Energy Gateway 2)

Hi, I’m just looking for information on how the Telsa gateway API handles it’s local password requirements, I’ve tried multiple variants of the options provided in the connection instructions for the integration, but it repeatedly just returns a variant of ‘unable to authenticate’ (not unable to connect, so I do know that I’m at least attempting to connect to the correct device) Since the ‘password’ is apparently the last 5 digits of the password marked in the chassis, I’m guessing it is not possible to change this and that it’s hard coded somewhere?

Also does anyone know if the local Access API is, or can be locked, and that is causing my issue?

Thanks for everyone’s time.
