Xiaomi Air Purifier Pro issue

Hello,

I have an issue with adding Xiaomi Air Purifier Pro on HA 2021.9;
I tried both automatic adding using Xiaomi Miio integration (& login to xiaomi account, selecting device) & manual by providing IP & token (token obtained using Cloud Token Extractor).

All attempts end with non-informative error:

There is nothing in the logs that shows any kind of errors/warnings that could indicate issues.

Anyone had similar issues?
