Google does not index the page even having WAF rules in ASN of Go
What steps have you taken to resolve the issue?
My problem is that to calculate the speed of the Cloudflare analysis from the observatory it causes a 403 error, in addition Google does not index the pages and when doing a URL inspection it causes an error
Sometimes happesn if the Website is recently added to your Cloudflare account, otherwise some Custom WAF Rule or other Security feature is blocking the requests from Google Cloud Platform ASN where the Tool itself is being used.
You should be able to see the challenged or blocked event under the Security tab → Events at Cloudflare dashboard for your zone and know exactly which security option was triggered.
Once you find them, click on a particular one to find more details about it (user-agent, IP, HTTP version …). If yes, could you share some details which service was triggered that blocked you?
I cannot reproduce the same as of currently it is proxied and using Cloudflare, therefrom no error shown on two tool tests:
