Failed to authenticate to Pixiv; Invalid grant_type parameter

[ghost]

Ever since updating my accounts username/password, I've been unable to authenticate to Pixiv with PixivPy.

I've tried changing my username a second time, shortening the password, and so on, but I'm still no longer able to authenticate no matter what I do.

I am certain the username and password being supplied are correct, but it is still returning this error:
