If this site does not belong to you, you will need to contact the site owner regarding their security settings. The Cloudflare Community has no insight into any changes a site owner might make.
So this is not a CF wide policy, and they may just put
this mandatory check ?
Site managers said they did not change anything, but
i still getting ip restriction.
I had also checked my ip for blacklisting, and clear.
So could been happened ?
This definitely sounds like the site owner or administrator enabled some checks or rules.
Can you visit https://testip.geekzone.co.nz and let us know if you get the captcha and if you note the ray id and let me know so I can find out why it happened.
Cloudflare no longer uses recaptcha. It’s been replaced by hcaptcha. But again, you need to get the site owners to look into their Cloudflare settings and firewall events log to see why you’re being challenged.
