40N FileNotFoundException for a valid url request HTTP GET

I have the following code to execute a GET request at the following URL:

http://rt.hnnnglmbrg.de/server.php/someReferenceNumber

However, here is my conclusion from Logcat:

java.io.FileNotFoundException: http://rt.hnnnglmbrg.de/server.php/6

Why does it return 404 when the url is explicitly valid?

Here is my connection code:

/**
 * Performs an HTTP GET request that returns base64 data from the server
 * 
 * @param ref
 *            The Accident reference
 * @return The base64 data from the server.
 */
public static String performGet(String ref) {
    String returnRef = null;
    try {
        URL url = new URL(SERVER_URL + "/" + ref);
        HttpURLConnection con = (HttpURLConnection) url.openConnection();
        con.setRequestMethod("GET");

        BufferedReader reader = new BufferedReader(new InputStreamReader(con.getInputStream()));

        StringBuilder builder = new StringBuilder();
        String line;
        while ((line = reader.readLine()) != null) {
            builder.append(line);
        }

        returnRef = builder.toString();

    } catch (IOException e) {
        e.printStackTrace();
    }
    return returnRef;
}

When you request a URL, it actually returns an HTTP code 404, which means that it was not found. If you have control over a PHP script, set the header to 200to indicate that the file is found.

404, . , - :

HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setRequestMethod("GET");
con.connect () ; 
int code = con.getResponseCode() ;
if (code == HttpURLConnection.HTTP_NOT_FOUND)
{
    // Handle error
}
else
{
    BufferedReader reader = new BufferedReader(new InputStreamReader(con.getInputStream()));

    // etc...
}
