So whenever I try to use fetch_feed with urls like the one below, I get back "WP HTTP Error: cURL error 28: Operation timed out after 30070 milliseconds with 0 bytes received" However when I use just a plain cURL on the url get a response. So I can only conclude something in Fetch Feed is the issue. Anyone have a better idea how to get past this issue?

include_once( ABSPATH . WPINC . '/feed.php' );
$feed_url = 'https://www.cbc.ca/podcasting/includes/frontburner.xml';
$rss = fetch_feed( $feed_url );
var_dump($rss);

Edit: I did some digging in the fetch_feed function, and found it worked when I commented out

$feed->set_file_class( 'WP_SimplePie_File' );

Any reason that could be? Any way to make this change in the theme file so it's not changed when wordpress is updated?
