I set up a firewall rule that states if not the United State and not a known bot then Challenge. But, on Facebook, the preview started showing “Attention Required! | Cloudflare”.
To fix this, I added… and not “facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)”. I tried the debugger, and this seems to work. However, is this the best way to fix the problem?
I run a very local website that does not seek or need traffic outside of the U.S. and it is starting to get hammered by Countries labeled T1 and Unknown.
