Connection timed out
I want to test this code which establishes SSL connection with the
server. Why it throws the exception as below. Also, how to retrieve
the content of the desired page on that host?:

System.out.flush();

out.flush();

String line;
while ((line = in.readLine()) != null)
System.out.println(line);
sslsock.close();
}
}
