InputStream in = null;
try

//this is giving timeout error
URL url = new URL("https", "host name/ip address", 443, "file name to download");
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();

/*
//This is working properly
URL url = new URL("valid url string");
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
*/

conn.setConnectTimeout(5000000);
System.out.println(conn.getConnectTimeout());

conn.setReadTimeout(5000000);
System.out.println(conn.getReadTimeout());

in = conn.getInputStream();
out = new BufferedOutputStream(new FileOutputStream("file name to download"));

byte[] buffer = new byte[1024];
int numRead;
long numWritten = 0;
while ((numRead = in.read(buffer)) != -1)
{
out.write(buffer, 0, numRead);
numWritten += numRead;
}
System.out.println("file downloaded: " + "\t" + numWritten);
}
catch (Exception exception)
{
exception.printStackTrace();
}
finally
{
try
{
if (in != null)
