Hi

After i cleared cache i got this error only in my back-office (file_get_contents_curl failed to download http://api.prestashop.com/xml/tab_modules_list_17.xml : (error code 7) Failed to connect to api.prestashop.com port 80: Connection refused) but the front-office is working fine, i deleted the files from cache but it's same and also i modified these 2 lines which i found in github:

curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 150);

curl_setopt($curl, CURLOPT_TIMEOUT, intval($curl_timeout) + 50); in tools.php and always the same problem.

Prestashop version 1.7.6.6

PHP version: 7.2

Thank you
