How to check status for 221g Admin processing

Can some please tell how to check the status based on case no. Right now I am using this link – https://ceac.state.gov/CEACStatTracker/Status.aspx?eQs=WwjqOlbeRYzCYubaSQI+RA== and entering my application Id.
But when I enter my case ID , it says its invalid. Can some please help me here. I have been waiting for 3 months now.

Hi,

You can check the status using your DS-160 confirmation code also.in the same site you had mentioned.
