Cloudflare block google bot

Hello everyone
I am using Cloudflare for almost 2 years and everything in my website was working good, but since on 17 June I have noticed that something is wrong. In first place my website started to have very few visitors in google analytics and I am earning less money in adsense. I talked about this with my hosting and they told me that problem can be in Cloudflare, however I haven’t changed anything in Cloudflare, but when I open security settings in Cloudflare I can see a JS Challenge (Modo bot fight) for some IP, many of them from USA. For example

  • Id. de rayo: 727da218acc9c175`
  • Método: GET
  • Versión HTTP: HTTP/2
  • Servidor:
  • Ruta:
  • Cadena de consulta: Cadena de consulta vacía
  • Agente de usuario: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.190 Safari/537.36
  • Dirección IP: 54.198.19.28
  • ASN: AS14618 AMAZON-AES
  • País : United States

example 2:

  • Id. de rayo 727d832eb9df3811
  • Método: GET
  • Versión HTTP: HTTP/1.1
  • Servidor:
  • Ruta:
  • Cadena de consulta: Cadena de consulta vacía
  • Agente de usuario: ias-va/3.1 (+https:// www. admantx. com/service-fetcher. html)
  • Dirección IP: 2600:1f18:d7f:1900:ab48:d58c:1f62:de05
  • ASN: AS14618 AMAZON-AES
  • País: United States

How I can know if Cloudflare is blocking Google bot?

These requests are not from Googlebot.

Verifying Googlebot

Before you decide to block Googlebot, be aware that the user agent string used by Googlebot is often spoofed by other crawlers. It’s important to verify that a problematic request actually comes from Google. The best way to verify that a request actually comes from Googlebot is to use a reverse DNS lookup on the source IP of the request, or to match the source IP against the Googlebot IP ranges.
