Exception in http url connection setup

Question

I have encountered an exception on connection.connect().I have attached the output of my logcat. There is mentioned about Run time exception.I have tried to run this service on thread but still the exception is occuring. I don't know why it is caused. Please inform Why this exception has occurred and How can I fix it.

Code:

public class TimeZoneDownloadingService extends Service {

    private IBinder mBinder  = new myBinder();

    @Override
    public void onCreate() {
        super.onCreate();
        showMessage("Service Started");


    }
    private void showMessage(String message)
    {
        Toast toast = Toast.makeText(this, message, Toast.LENGTH_LONG);
        toast.show();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        showMessage("StartCommand");
        //return super.onStartCommand(intent, flags, startId);
        Thread thread = new Thread(new Runnable(){
            public void run(){
                StartDownloadTimezone();
            }
        });
        //thread.start();

        thread.start();
        return START_NOT_STICKY;
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        showMessage(" on Bind");
        return mBinder;
    }


    @Override
    public void onTaskRemoved(Intent rootIntent) {
        super.onTaskRemoved(rootIntent);
        stopSelf();
    }
    public class myBinder extends Binder {

        TimeZoneDownloadingService getService()
        {
            return TimeZoneDownloadingService.this;
        }

    }
    public void StartDownloadTimezone()  {
        HttpURLConnection connection = null;
        InputStream  stream = null;
        try{
            URL url = new URL("https://api.timezonedb.com/v2.1/list-time-zone?key=P8B5V3KL22GA&format=json&country=US");
            connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setDoInput(true);
            connection.setDoOutput(true);
            connection.connect();

            stream = connection.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(stream));
            StringBuffer buffer = new StringBuffer();

            String line = " ";
            while((line = reader.readLine()) != null)
            {
                buffer.append(line);
            }
            parse(buffer);
            showMessage("URL connection successful");


        }catch(Exception exception)
        {
            exception.printStackTrace();
        }

    }
    private void parse(StringBuffer buff)
    {
        showMessage("Parsing");
    }


}

Remove your `Toast`. Do something else, such as a `Log` call to log a message to Logcat. — CommonsWare, Jun 12 '21 at 17:12
Try commenting the line `parse(buffer);` and [change your TLS](https://stackoverflow.com/a/61559588/10534012). — Darkman, Jun 12 '21 at 20:19
