URL:Blacklist - api

Hello, I am part of the software development team in the state of Ceará, recently one of our services was blacklisted. I would like to know why so we can fix the problem. Doing a scan I realized that the url was in the CRDF but once I scan it in the CRFD itself it doesn’t count the url as malicious.
the url is
https://api-fardamento.pm.ce.gov.br/
