Unable to track my 221g administrative processing case

Hi all, I had my visa interview on 20th April 2021 and received 221g white slip and the VO provided me with a case number. but when i am trying to check my case status on https://ceac.state.gov/CEACStatTracker its showing me “your search did not return any data” i entered the space between the case number properly. i even tried with my DS160 application ID and still its showing “No status”. can someone please help me with this?
