Xiaomi Miio Integration not working

I tried to configure the integration by entering my username/password but received an error at first. Then I grabbed the tokens for the two of the smart plugs I have and tried to configure manually and got this message:

After a bit more fiddling, I was able to login with my credentials, when then gave me the two plugs to select from, but when I chose one and clicked next I got the same error message. I restarted HA, still no dice.

Any ideas?
