Frequently Getting the Error Message "too many requests"

Within the last 2 months the error message "too many requests" has started showing up for those using my site. The site is hosted on a server with a 32 core CPU and 64 GB of RAM. The site usually only uses 10% of the CPU and 15% of the RAM. I do not have Mod_Evasive installed on the server. In the my.cnf file I have max_connections set to 3000. I recently changed the PHP-FPM Max Requests from 20 to 200 and this only seemed to make the error message appear more. I do have all traffic going through CloudFlare, so as far as the server is concerned, all of the traffic is coming from CloudFlare IP addresses. I also use CloudFlare to cache front-end content to reduce the strain on the server. Is there anything in cPanel/WHM that produces the error message "too many requests" besides Mod_Evasive? Any help on this would be greatly appreciated. cPanel/WHM Version:110.0.10 OS: CentOS v7.9.2009
