javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x7fa2258640: Failure in SSL library, usually a protocol error

I am trying a demo Android app to connect servlet (both local server and aws instance) it gives Handshake failed error. I have tried with volley and http client also. The relevant code and logcat result is following. Currently I am using Android version 7.1 and redmi 5A cellphone for testing.

import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import java.io.BufferedReader;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import java.net.URL;import java.net.URLConnection;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        execute();    }    void execute() {        new Thread(new Runnable() {            public void run() {                try {            URL url = new URL("https://192.168.0.7:9999/WebS/welcome/test");            URLConnection connection = url.openConnection();            String inputString = "hello server";            //inputString = URLEncoder.encode(inputString, "UTF-8");            Log.d("inputString", inputString);            connection.setDoOutput(true);            OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());            out.write(inputString);            out.close();            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));            Toast.makeText(MainActivity.this, in.toString(), Toast.LENGTH_LONG).show();            in.close();        } catch (Exception e) {            Log.e("YOUR_APP_LOG_TAG", "I got an error", e);        }    }}).start();}}

Logcat result:
