Cloudflare is blocking you because its security systems have detected something about your connection or activities that matches threat patterns or violates a website’s protective rules. This can happen for several different reasons, many of which are intended to safeguard sites from malicious behavior, spam, or automated attacks.

Common Reasons for Blocking

• Suspicious IP Reputation : If your IP address has been flagged for past malicious activity or is part of a shared network with bad actors, Cloudflare may block you.

• High Security Settings : Website owners may set strict security rules that block legitimate users by mistake, especially during web attacks or periods of heightened alert.

• Rate Limiting : Making too many requests (e.g., rapidly refreshing a page) can trigger automatic blocks designed to prevent scraping or Denial-of-Service attacks.

• Browser or User Agent Issues : Using unusual browsers, outdated software, or customized user agent strings can make Cloudflare suspect you’re a bot or attacker.

• VPN or Proxy Usage : If you’re accessing the website through a VPN or proxy whose IP is on a blocklist, Cloudflare may restrict your access.

• Firewall or Custom Rules : Some websites set up special Cloudflare firewall rules to block specific visitors, countries, or networks.

• Bot Protection Measures : Cloudflare might display a CAPTCHA challenge or block if it thinks your visit looks automated or suspicious.

• Country or Region Blocking : Certain sites restrict access from specific geographic areas.

What You Can Do

• Clear your browser cache and cookies, then try again.

• Disable your VPN or proxy and attempt to reconnect, as IP reputation is a frequent blocker.

• Update your browser and use default settings to minimize suspicion.

• If caught in a CAPTCHA loop, complete the challenge or switch networks to see if the block is network-specific.

• Contact the website owner if access remains denied so they can review and possibly whitelist your connection.

Cloudflare’s blocking measures are designed to maintain the safety and integrity of websites, but sometimes they inadvertently affect legitimate users.
