New Feedback Tool does not work

Tried to create an account there using e-mail address (to upvote), but at the end of the process, I was redirected to a missing page ( When I try to login now, nothing happens. When I try to create the account again, it says it already exists. When I try to upvote something, it requires me to login, when I do so, nothing happens and my upvote is not counted in.

Am I the only person having trouble with this?
