I have an account for my sites. It is forcing viewers to complete a Captcha on my sites in Chrome in Mexico. My other account does not force the captcha. Haven’t changed the settings, no idea how to fix. Sites are ok in Firefox.
It’s interesting that it’s only happening in Chrome. Have you taken a look at Firewall Events Log to see if any of those challenges are logged? It would show which setting triggered it.
Tried it in Brave, Chrome, Vivaldi and incognito. It’s in the Chrome dna. I see the site ok but friend in Mexico gets captcha every visit. If I move the site to his CF all is good for both of us. Tried making a new CF account - captcha again. Free account, no fancy settings same settings in Mx and NZ accounts.
