I tested the version of the php code that brings certain information to the console to do tests and it works perfectly.

I tested php code with cURL for simplified test but I get the same error
<?php

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

// Execută cererea cURL
$response = curl_exec($curl);
curl_close($curl);

// Verifică dacă cererea a reușit
if ($response) {
    // Caută titlul în răspunsul HTML
    if (preg_match('/<title>(.*?)<\/title>/', $response, $matches)) {
        $title = $matches[1];
        echo "Titlul paginii este: " . $title;
    } else {
        echo "Nu s-a putut găsi titlul în HTML.";
    }
} else {
    echo "Cererea cURL a eșuat.";
}
