If you get this error while visiting someone else’s website, I am afraid you cannot do anything. You can try to access it using a VPN or over a TOR, but I do not guarantee because it could also be blocked and restricted.
Obviously the website owner is using Cloudflare and security options available to him to protect his website.
Maybe you have had some bad requests, or the owner decided to deny the requests comming from your country, etc.
The site can block for any number of reason, that’s up to them and not something this Community nor Cloudflare can do anything about.
