Hi Jose.
I get no error when I search for extension updates from the core.
I checked if the following program can connect to the update server from the site server.
;;;;;;;;;;;;;
<?php
echo '<p>access test</p>';
$starttime = date("Y-m-d H:i:s") . "." . substr(explode(".", (microtime(true) . ""))[1], 0, 3);
echo 'Start Time:'.$starttime;
$xml_url="
securitycheck.protegetuordenador.com/upd...securitycheckpro.xml";
$sc_xml = file_get_contents($xml_url);
echo '<br>
<br>';
echo $sc_xml;
echo '<br>
<br>';
$endtime = date("Y-m-d H:i:s") . "." . substr(explode(".", (microtime(true) . ""))[1], 0, 3);
echo 'End Time:'.$endtime.'<br>';
?>
;;;;;;;;;;;;;
The result is displayed as below, and it took to access within 1.0 seconds.
