This is my code in java, and when i call it he return 401, i need something more?

private boolean checkTwitchLiveStatus() {
        String clientId = "the_client_id_from_the_app_manager";
        String channelName = "my_channel_name";

        try {
            URL url = new URL("https://api.twitch.tv/helix/streams?user_login=" + channelName);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");
            conn.setRequestProperty("Client-ID", clientId);
            conn.setRequestProperty("Accept", "application/vnd.twitchtv.v5+json");

            int responseCode = conn.getResponseCode();
            System.out.println("Codice di risposta dell'API di Twitch: " + responseCode); //responseCode is the code 401

            if (responseCode == HttpURLConnection.HTTP_OK) {
                BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                StringBuilder response = new StringBuilder();
                String line;
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();

                String jsonResponse = response.toString();
                System.out.println("Risposta JSON dall'API di Twitch: " + jsonResponse);

                return jsonResponse.contains("\"type\":\"live\"");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        return false; // Default: live non attiva
    }
