Power BI Report Server 404 Not Found after removing HTTP URL Reservation

Hi,
I have been asked to remove possibility to access report via HTTP on Report Server.
I have removed reservations for address REPORTServerURL.COMPANY.COM and just leave REPORTServerURL.COMPANY.COM on HTTPS Section.

But after that whenever I try to access Power BI Reports on report server (open it or try to Manage it) i am getting generic Error on Browser.

Inside the LOG file i can find :

2021-06-11 12:59:13.4679|ERROR|6|OData exception occurred: System.Net.WebException: The remote server returned an error: (404) Not Found.
