 * [1 week, 1 day ago](https://wordpress.org/support/topic/cloudflare-connection-issues/)
 * I got the “An error occurred and we were unable to load the data from the server.”
   error in WF central
   I whitelisted the listed IP’s, 54.68.32.247, 44.235.211.232,
   54.71.203.174 as well as other whitelisting. But error does not clear. Other 
   sites on the same server that are not on Cloudflare have no issues.Is there any
   other whitelisting I am missing?ThanksDaveed

 * Hi [@flexer](https://wordpress.org/support/users/flexer/),
 * Whilst you’ve added [our IPs](https://www.wordfence.com/help/advanced/#servers-and-ip-addresses)(
   although still check some information in that link if you haven’t seen it already),
   ensure your server’s own IP is also added to prevent loopback issues: [https://www.wordfence.com/help/advanced/compatibility/#cloudflare-compatibility](https://www.wordfence.com/help/advanced/compatibility/#cloudflare-compatibility)
 * IP detection at **Wordfence > All Options > General Wordfence Options > How does
   Wordfence get IPs** should use our “**Use the Cloudflare “CF-Connecting-IP” HTTP
   header to get a visitor IP. Only use if you’re using Cloudflare.**” if it isn’t
   already: [https://www.wordfence.com/help/dashboard/options/#general-wordfence-options](https://www.wordfence.com/help/dashboard/options/#general-wordfence-options)
 * Let us know how you get on,
   Peter.
