Connection timed out: connect 에러가 발생합니다 조언부탁드려요

Question

URL obj = new URL(url);

HttpURLConnection conn = (HttpURLConnection) obj.openConnection(proxy);

conn.setRequestProperty("Content-Type", "application/json");

conn.setDoOutput(true);

conn.setRequestMethod("GET");

conn.setRequestProperty("Cookie", coockie);

conn.setConnectTimeout(5000); //서버에 연결되는 Timeout 시간 설정

conn.setReadTimeout(1000); // InputStream 읽어 오는 Timeout 시간 설정

conn.setRequestProperty("Authorization", authHeader);

br = new BufferedReader(new InputStreamReader(conn.getInputStream() ,"UTF8"));

에러 코드입니다.

연결이 안된것입니다.

connection refused는 IP는 연결되나 port 연결 안된경우이고

Connection timed out인경우는 대부분 서버 방화벽을 막아 버린 경우가 대부분입니다.
