GDAX Java Bad Request

GDAX Java Bad Request

Trying to request private data on GDAX but keep getting bad request. Cannot figure out what I am doing wrong. Please help.

private static JsonObject getAuthenticatedData() {
        try {

            String accessSign = getAccess();
            System.setProperty("http.agent", "Java Client");

            URL url = new URL("http://ift.tt/2jaFBMq");
            HttpURLConnection con = (HttpURLConnection) url.openConnection();
            con.setRequestMethod("GET");

            con.setRequestProperty("CB-ACCESS-KEY", "accesskey");
            con.setRequestProperty("CB-ACCESS-SIGN", accessSign);
            con.setRequestProperty("CB-ACCESS-TIMESTAMP", ""+System.currentTimeMillis() / 1000L);
            con.setRequestProperty("CB-ACCESS-PASSPHRASE", "passphrase");
            con.setRequestProperty("Content-Type", "application/json");


            con.setConnectTimeout(5000);
            con.setReadTimeout(5000);

            String status = con.getResponseMessage();
            System.out.println(status);

            BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
            String inputLine;
            StringBuffer content = new StringBuffer();
            while ((inputLine = in.readLine()) != null) {
                content.append(inputLine);
            }
            System.out.println(content);
            in.close();

            con.disconnect();

        }catch(Exception e) {
            e.printStackTrace();
        }
        return null;


    }

And this:

public static String getAccess() {

    //Set the Secret
    String secret = "secret==";
    //Build the PreHash
    String prehash = Instant.now().toEpochMilli()+"GET"+"/accounts";
    String hash = null;
    try {

        Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
        SecretKeySpec secret_key = new SecretKeySpec(secret.getBytes(), "HmacSHA256");
        sha256_HMAC.init(secret_key);

        hash = Base64.encodeBase64String(sha256_HMAC.doFinal(prehash.getBytes("UTF-8")));
         hash = hash.replace("\n", "");
        System.out.println(hash);
       }
       catch (Exception e){
           e.printStackTrace();
       }
    return hash;   
}
