Nix / NixOS

I've been trying to create a public instance of SearXNG by using NixOS, Cloudflare and Nginx, but I can't seem to make it open to the internet and I've ran out of ideas. Is there anything I'm overlooking?

services.searx = {
    enable = true;
    redisCreateLocally = true;
        limiterSettings = {
      real_ip = {
        x_for = 1;

        ipv4_prefix = 32;
        ipv6_prefix = 56;
      };
    botdetection = {
        ip_limit = {
          filter_link_local = true;
          link_token = true;
        };
        ip_lists = {
          pass_ip = [
            "192.168.0.0/16"
            "fe80::/10"
          ];
          pass_searxng_org = true;
        };
      };
    };
    runInUwsgi = true;
    uwsgiConfig = {
      socket = "/run/searx/searx.sock";
      http = ":8888";
      chmod-socket = "660";
      disable-logging = true;
    };
    settings = {
      general = {
        debug = false;
        instance_name = "SearXNG Instance";
        donation_url = false;
        contact_url = false;
        enable_metrics = false;
      };

      ui = {
        static_use_hash = true;
        theme_args.simple_style = "dark";
        query_in_title = true;
        center_alignment = true;
        results_on_new_tab = false;
      };

      search = {
        safe_search = 2;
        autocomplete_min = 2;

        default_lang = "en-US";
        base_url = "https://myinstance.org";
        public_instance = true;
      };
      engines = lib.mapAttrsToList (name: value: {inherit name;} // value) {
        "duckduckgo".disabled = false;
        "brave".disabled = true;
      };
      outgoing = {
        request_timeout = 5.0;
        max_request_timeout = 15.0;
        pool_connections = 100;
        pool_maxsize = 15;
        enable_http2 = true;
      };
    };
  };

    virtualHosts = {

        sslCertificate = config.sops.secrets."SSL-Certificates/Cloudflare/Cert".path;
        sslCertificateKey = config.sops.secrets."SSL-Certificates/Cloudflare/Key".path;
        locations = {
          "/" = {
            extraConfig = ''
              uwsgi_pass unix:${config.services.searx.uwsgiConfig.socket};
            '';
