Error: Forbidden

Getting this error every time I try to authenicate until cloudflare protection kicks in and blocks me.
Tried with [email protected], 1.3.0, 1.4.0. All have the same issue. This does not happen in mineflayer. I don't know what triggers it but sometimes it starts happening in mineflayer too.

ygg.auth({ username: u.username, password: u.password }, console.log);
