Hi. I’m trying to figure what causes a cURL error 28: Connection timed out after n milliseconds error
I installed query monitor and if I understand correctly
it suggests to install 2 plugins - but cornerstone is already installed and not sure about wordpress SEO. That one is not listed as plugin

1. Cornerstone_Updates->http_request_args()
   wp-content/plugins/cornerstone/includes/classes/admin/class-updates.php:192|Plugin installeren: cornerstone|
   |http_response|10|-

2. WPSEO_License_Page_Manager->handle_response()
   wp-content/plugins/wordpress-seo/admin/class-license-page-manager.php:101|Plugin installeren: wordpress-seo|

Hello @NCVA,

Thanks for writing to us

This problem is a very common server related issue. In most of the cases not created by a particular theme or plugin, nor by WordPress.

The first thing to do is to update your WordPress to the latest version if not already done.

Then if the problem is still there, contact your hosting company and ask the hosting support team to check the following points.

• Make sure your server is running a recent version of PHP and the cURL library

• Try to increase your Server Memory Limits settings.

• The cURL error can be a DNS related issue. Your hosting company might need to switch DNS configuration to OpenDNS : https://www.howtogeek.com/164981/how-to-switch-to-opendns-or-google-dns-to-speed-up-web-browsing/

• Ask your host if there is some limitation with wp-cron, or if loopback is disabled.

• Ask your host if there a firewall or security modules (e.g. mod_security ) that could block the outgoing cURL requests.
