如何在AWS上托管nanohttpd java应用程序？

我用nanohttpd编写了简单的hello world http服务器应用程序：

package name.antonsmirnov.apptogether.service.http;

import fi.iki.elonen.NanoHTTPD;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.IOException;
import java.util.concurrent.atomic.AtomicInteger;

/**
 * HTTP server
 */
public class HttpSample {

    private static Logger logger = LoggerFactory.getLogger(HttpSample.class);

    private NanoHTTPD server;
    private int port;
    private String host;

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }

    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }

    private AtomicInteger counter = new AtomicInteger(0);

    private void initHttp() {
        server = new NanoHTTPD(host, port) {
            @Override
            public Response serve(IHTTPSession session) {
                String ip = session.getHeaders().get("http-client-ip");
                logger.info("Request from " + ip);
                String message = "hello " + ip + " " + counter.incrementAndGet();
                return newFixedLengthResponse(Response.Status.OK, MIME_PLAINTEXT, message);
            }
        };
    }

    /**
     * Start HTTP server
     * @throws Exception
     */
    public void start() throws Exception {
        if (started)
            return;

        initHttp();
        started = true;

        doStart();
    }

    private void doStart() throws IOException {
        logger.info("Starting at port {} ...", port);
        server.start();
        logger.debug("Started");
    }

    /**
     * Stop HTTP server
     * @throws Exception
     */
    public void stop() throws Exception {
        if (!started)
            return;
        started = false;

        doStop();
    }

    private void doStop() {
        logger.info("Stopping ...");
        server.stop();
        logger.debug("Stopped");
    }

    private boolean started;

    public boolean isStarted() {
        return started;
    }

    public static void main(String[] args) {
        HttpSample httpSample = new HttpSample();
        httpSample.setPort(5555);
        httpSample.setHost("0.0.0.0");

        try {
            httpSample.start();
        } catch (Exception e) {
            logger.error("Failed to start", e);
            return;
        }

        try {
            Thread.sleep(Long.MAX_VALUE);
        } catch (InterruptedException e) {
            logger.error("Interrupted");
        }
    }
}

但这在中国是遥不可及的

我在日志中看不到请求（我应该可以在本地主机上看到smth，如

00:59:25.864[NanoHttpd请求处理器（#1）]信息HttpSample$1-来自x.y.z.k的请求）。相反，我看到错误连接超时错误

怎么了？我是否应该以某种方式为VPC配置端口？它与nginx冲突吗？
我刚刚允许安全组中的端口5555上的传入请求：


如果我决定使用端口80，不确定它是否与nginx冲突
