This has been happening since. A few weeks ago, secondary account went down too, yielding the same error OP got.
Note: a) I have been using the same IP and the same machine to log into those accounts for many years; there is no other device or location where I've signed in before! b) primary account has multiple (4) Yubikeys associated with it, so it should be clear I'm a real person and not a bot.
I'm currently in panic mode: if my main account goes down, it will take a huge part of my life with it, from banks to government stuff.
