How to get Amazonalexacontrol to connect to Australian Amazon servers?

im trying to set up Alexa binding in Openhab2, but im getting a “http Error 500, Server Error”

Looking over things, i believe the error comes from the fact that the amazonalexacontrol trys to connect to the server, but our account is registered in Australia,.

is there a way of getting the amazonalexacontrol to connect to the Australian Amazon servers instead of the US Amazon servers?
