How to get SRC from this site?

Question

Need your Help. I try to get SRC from site, but always get empty String. Whast I am doing wrong? My code:

try {
            Document pageMeteo = Jsoup.connect("https://radar.veg.by/kiev/")
                    .userAgent("Chrome/4.0.249.0 Safari/532.5")
                    .referrer("http://www.google.com")
                    .get();
            Element strImgHtml = pageMeteo.select("#scroller > div:nth-child(1) > div:nth-child(1) > img:nth-child(1)").first();
            Elements strToGetImg = strImgHtml.getElementsByTag("img");
            String src = strToGetImg.attr("scr");
            if(src.isEmpty()){
                sendMsg(message, "This str is empty!");
                System.out.println("This str is empty!");
            }else {
                sendMsg(message, src);
                System.out.println(src);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

Result is: This str is empty! ok, another code:

Elements strImgHtml = pageMeteo.select("#scroller > div:nth-child(1) > div:nth-child(1) > img:nth-child(1)");
            for (Element el : strImgHtml) {
                String src = el.attr("src");

Result is: This str is empty! ok, another way...

Elements strImgHtml = pageMeteo.select("#scroller > div:nth-child(1) > div:nth-child(1) > img:nth-child(1)");
            Element srcToGetImg = strImgHtml.select("img.[src$=.png]").first();
            String src = srcToGetImg.text();

Result: java.lang.IllegalArgumentException: String must not be empty At last:

Elements source = pageMeteo.select("#scroller > div:nth-child(1) > div:nth-child(1) > img:nth-child(1)");
            if(source.hasText()){
                System.out.println("text present");
            }else {
                System.out.println("no text");
            }
            
            Pattern p=null;
            Matcher m= null;
            String word0= null;
            String word1= null;

            p = Pattern.compile("<img[^>]*src=[\"']([^\"^']*)",
                    Pattern.CASE_INSENSITIVE);
            m = p.matcher(source.toString());
            while (m.find())
            {
                word0=m.group();
                System.out.println(word0.toString());
            }

            if (source.isEmpty()) {
                sendMsg(message, "This str is empty!");
                System.out.println("This str is empty!");
            } else {
                sendMsg(message, source.toString());
                System.out.println(source);
            }

Relust: no text org.telegram.telegrambots.exceptions.TelegramApiRequestException: Error sending message: [400] Bad Request: can't parse entities: Unsupported start tag "img" at byte offset 0
