Deleted Firewall rules but still there is issue with my website

I have created firewall rules related to country because I have encountered some bot behavior from certain countries, but this had affected my website because my website is also hosted on a shared hosting existing on that region, so I have deleted my firewall rules, but now still my website is not opening I have to try multiple refresh then in any one attempt my website opens, so anyone please tell me what should I do and how much it takes for a firewall to apply changes, please I have deleted my firewall rules 1 hour ago but still on some devices it is giving error, the error is as follows as you can see in the picture below:

Without knowing the actual URL, we can not assist. From what I see, that site isn’t even on Cloudflare.
