Alexa Integration: CannotAuthenticate: Forbidden error during volume changes (amazon.de)

[pedolsky]

The problem

Whenever the volume of an Echo device changes, the integration logs a Forbidden (403) authentication error. This happens while the system tries to fetch the history data from the German Amazon endpoint.
All media players and event entities don‘t update anymore.

Steps to Reproduce:

1. Connect Amazon/Alexa integration using a German account (amazon.de).
2. Change the volume on any Echo device.
3. Check the Home Assistant logs for the authentication error.
