CloudFlare HTTP DDoS

Hi everybody!
I have some HTTP DDOS problems…:
i use some hetzner proxies about 50-100, when i use it try on my friend’s cloudflare website it returns a status code 403, i checked and found that my hetzner proxies 100% blocked by http ddos with ruleid: 78da7447eca94fabbcb405fc923e2920 or: HTTP requests causing a high request rate to origin, i tried with some. proxies from other countries like japan, russian, vietnam… it’s not blocked by cloudflare, i only checked and found that only proxies with ASN24940 (hetzner) are blocked, I won’t be using it on every single one of my sites so I’m looking. forward to getting it fixed. as quickly as possible.
Thanks…
