 * Hi [@coachmarino](https://wordpress.org/support/users/coachmarino/),
 * Apologies for the delay!
 * This message means that our servers cannot connect to yours in order to optimize
   the pages. It is likely that there is an active firewall on your end. In such
   cases it is recommended to whitelist our server IPs in order to ensure proper
   operation.
 * An up to date list with our IPs can be found here: [https://help.nitropack.io/en/articles/3379008-ip-whitelisting](https://help.nitropack.io/en/articles/3379008-ip-whitelisting)
 * Hope this helps!
