I’ve a big problem. i Bought cloudflare firewall cause 3 months ago i was getting visitor spam on my WHMCS dologin.php path… i added a captcha, but still doesn’t work… so i added cloudflare and i mitigated the attack.
Now… i don’t know how, but they are bypassing my cloudflare. i’m getting again 100% CPU usage , they are spamming on www.mydomain.info/billing/dologin.php and website is crashing every minute.
i also cannot block their IP manually cause they are changing IP every action. I don’t know now how to fix… i solved by adding cloudflare…but now…
