[Help] Youtube.com not blocked

[Septias]

I want to block youtube, instagram, ... with blocky but it doesn't work sadly :/

This is my nix configuration:

blocky = {
      enable = true;
      settings = {
        upstreams.groups = {
          default = ["1.1.1.1" "8.8.8.8"];
        };
        ports = {
          http = 4000;
          https = 443;
        };
        blocking = {
          denylists = {
            ads = ["https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts"];
            social = ["${../social-blocking.txt}" ''
              instagram.com
              youtube.com
              facebook.com
              reddit.com
            ''];
          };
          allowlists = {
            music = ["${../music-allow.txt}"];
          };
          clientGroupsBlock = {
            default = ["ads" "social"];
          };
        };
      };
    };

The social blocking file has this content:

instagram.com
youtube.com
facebook.com
reddit.com

What am I missing to make this work?
