Domain blocking multiple IP adresses

I cannot access because I always get error code 1020. I have tried using a VPN or other IPs. I have also tried using multiple browsers and other devices, but still no progress.

While visiting a site protected by Cloudflare, error 1020 “Access denied (Error: 1020)” indicates you’ve violated a Firewall Rule. When this happens, you’ll see the error “Access Denied (Error: 1020)” and your request was blocked by the filter based Firewall rule on the site. If you’re the site owner, you can find the requests that was blocked by the Firewall on the Firewall page under the Events menu. See this #CommunityTip for suggestions to avoid this error,

As I’m not the site owner, is there any way to check the firewall rules?
Thank you.
