Hi!
In some cases, a site behind Cloudflare might be configured in a way that prevents our requests from going through even if they’re not being blocked by Cloudflare, but the error message will show that Cloudflare is blocking them because we’re unable to determine any other cause. You’ll definitely want to ensure that you’re using the latest version of the Wordfence plugin, and that the WordPress REST API is enabled on your site, as Central uses this to connect to the site.
Hi @manx203,
To add onto what Ram mentioned, it is possible that your site is blocking 54.68.32.247 and not CloudFlare.
Do you have any .htaccess rules that may be blocking a range of IPs?
