If you were using nostr:npub1us9uc0sjjg0vyvh7vefgu2a96hx5up5gujl6pqays65hlk4de6hsnwq4g0 earlier today and you were unable to backup / restore your account, I am sorry. It was broken. The authorization server service was offline and needed to be fixed. Don't fret! You can now safely backup and restore your accounts once more.
