I am trying to connect to the localhost port and I am getting the following error, how can I fix this error ?
" terminate called after throwing an instance of 'boost::exception_detail::clone_impl >' what(): connect: Connection refused "
#include <boost/asio.hpp>
#include <iostream>
int main() {
boost::system::error_code ec;
using namespace boost::asio;
io_service svc;
ip::tcp::socket sock(svc);
sock.connect({ {}, 3000 }); // localhost port
std::string response;
do {
char buf[2048];
size_t bytes_transferred = sock.receive(buffer(buf), {}, ec);
if (!ec) response.append(buf, buf + bytes_transferred);
} while (!ec);
// print and exit
std::cout << response <<std::endl;
}

You can't connect to a port with nothing listening to it. That's what Connection Refused means: "nothing is here to respond to your request."
You will have to run or use some other server for a connect() to succeed.
If you're using a unix like system, you can probably use a tool like socat to quickly throw together a service to listen on a port that you can then connect to.
