Error (Unable to connect to the Hestia APT repository)

Good time of day. I Have a dedicated IP address. I installed a clean Debian-11.4.0-amd64, an error came out during installation that it was impossible to connect to the Hestia APT repository. Made a ping , pings. Read similar topics realized that the dedicated IP address of my provider may be ban. Please, help me. Sent an email to [email protected] with my dedicated IP address.
