Audi Connect integration suddenly failing with http 400

Out of the blue, my audiconnect integration is now failing with:

2021-05-12 11:36:06 ERROR (MainThread) [custom_components.audiconnect.audi_connect_account] Login to Audi service failed: 400, message='', url=URL('')

I’ve checked the password in the core configuration, and I’m using the same creds on the iOS audiconnect app without any problems.

Before I go about wiping integrations and such, Is anyone else seeing this failure?

Thanks for any help.

Any resolution to this? I’ve just got my Audi back from the shop, it must have had a big system reset and lost MMI information, now that I’ve configured AudiConnect, Homeassistant no longer loads properly, but I don’t know what may have caused it.

I recently tried to reinstall audiconnect, and/but I can no longer get my credentials validated. (website and iOS app works fine with same creds). I’m at 2021.5.something. I’m about to give up and go back to my bluetooth beacon method of tracking the cars…
