DOM is no longer supported because it suddenly stopped working?

I made my page year ago and i retrieve the code from another website

Can anyone tell me why it suddenly stopped working, I haven’t made any changes to the site for a year?

Here is my code

<?php
require ('php/simple_html_dom.php');

$html = file_get_html ("https://www.aviationweather.gov/metar/data?ids=epkk");

echo $html->find("code",0)->innertext;

?>
