I know 403 is completely a server issue and not from cloudflare but something strange is happening. Sites which are using Cloudflare and using cPanel are causing 403 error. Once I disabled and remove the NS of cloudflare the site doesn't give a single 403 error.
cPanel + Cloudflare enable > on multiple refresh sometime site loads without 403 error but mostly 403.
cPanel - Cloudflare disable > site work fine without any 403 error.
cPanel version is 88.06 (tested with these domain tlds .net, .co, .com)
I am unable to diagnose the cause, if someone having same issue please let me know how you resolved it?
