I don't think there's any point in posting a screenshot of this error message. By the way, the security guard ID is 3e8e9973. As I said, this is the email address and pass that I was able to log in to just before, so there can't be any input errors.

このエラーメッセージのスクショ貼る意味ないと思うけどね
因みに警備員IDは3e8e9973です

言った通り直前までログイン出来てたメアドとパスだから入力誤りはあり得ないです
