java.net.SocketException：当我从Java连接到MongoDB 4.0时，未实现未连接的套接字

Question

当我尝试使用ssl=true从Java连接MongoDB 4.0时，出现以下错误：

Timed out after 30000 ms while waiting to connect. Client view of cluster state is {type=UNKNOWN, servers=[{address=10.0.1.182:27017, type=UNKNOWN, state=CONNECTING, exceptio

SSLSocketFactory创建：

SSLSocketFactory createSSLSocketFactory() throws SAXException, IOException, DocumentException,
        ParserConfigurationException, NoSuchAlgorithmException, NullPointerException, KeyStoreException,
        UnrecoverableKeyException, CertificateException, KeyManagementException {

    SSLContext sslcontext = SSLContext.getInstance("TLS");

    KeyStore ks = KeyStore.getInstance("JKS");
    ks.load(new FileInputStream(new File("/home/ubuntu/keystore.jks")), "password".toCharArray());

    KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
    kmf.init(ks, "password".toCharArray());
    TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
    tmf.init(ks);

    sslcontext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);

    return sslSocketFactory;
}
