Authentication Error 401 appeared after a few days

[ElZorroofOz]

Hi there,
Downloaded a 3-4days ago, very happy, seemed to work fine (apart from getting version 0.14 from pip3, not 0.16).
Using on Raspberry Pi3 to integrate charging with my solar load controller. No HA integration. Python 3.7.
All going well, then after maybe 24hr , cannot authenticate anymore. Error 401, but the credentials are correct (set in a script, and the website and the bmw app still work).
Looked everywhere following the trace below, can't make sense of it - it feels there has been a timeout somewhere as it worked perfectly for a while.
Traceback:
DEBUG:asyncio:Using selector: EpollSelector
MyBMWAuthError due to HTTPStatusError: invalid_client - Client authentication failed (e.g., login failure, unknown client, no client authentication included or unsupported authentication method)
Traceback (most recent call last):

The above exception was the direct cause of the following exception:

Any suggestion ?
Thanks !

Feels like it's the same issue as #671

Yes, it is
