So, if Cloudflare is blocking you, it’s likely because the security settings on the website you’re trying to access have identified your connection as potentially suspicious or harmful.


Why Cloudflare is Blocking you

Below are some  of the common reasons for Cloudflare blocking your access include:

IP reputation

Cloudflare mantém uma lista de endereços IP conhecidos por spam, tentativas de hacking ou outras atividades maliciosas. Se o seu endereço IP estiver nessa lista ou tiver uma reputação ruim, você poderá ser bloqueado.

High-security settings

O proprietário do site pode ter definido suas configurações de segurança do Cloudflare em um nível alto, causando uma filtragem mais agressiva do tráfego de entrada. Nesses casos, até mesmo usuários legítimos podem ser bloqueados ou desafiados.

Rate limiting

Cloudflare can block or limit access from IP addresses that make too many requests within a short period, as this can indicate a DDoS attack or automated scraping attempts.

Browser or User-agent issues

Using an outdated browser, a non-standard user agent, or having disabled cookies and JavaScript might trigger Cloudflare’s security measures.

VPN or Proxy usage

O uso de VPNs, proxies ou Tor pode, às vezes, fazer com que a Cloudflare sinalize sua conexão como suspeita, pois essas ferramentas são frequentemente usadas para ocultar atividades mal-intencionadas.

Firewall rules

O proprietário do site pode ter definido regras específicas de firewall na Cloudflare que bloqueiam determinados endereços IP, países ou agentes de usuário.

Error warnings you might experience

You might see a warning like this:

“We are currently experiencing a high level of malicious traffic from your country and have had to temporarily restrict access to our website from your location.”

How to fix Cloudflare blocking you:

Para resolver o problema, você pode tentar o seguinte:

  1. Limpar seu navegador cache e cookies, e garanta JavaScript está ativado.
  2. Atualize seu navegador to the latest version, or try using a different browser.
  3. Temporariamente desativar sua VPN or proxy if you are using one.
  4. Check your internet connection and restart your modem or router to obtain a new IP address.
  5. If you suspect your IP address has been mistakenly flagged, you can contact the website owner ou o suporte da Cloudflare para solicitar uma revisão de seu endereço IP.
  6. Conecte-se a partir de seu telefone ou acesse o site em uma cafeteria local.

Lembre-se de que essas medidas estão em vigor para proteger os sites e seus usuários contra ameaças à segurança. Embora o bloqueio possa ser frustrante, a intenção é manter um ambiente on-line seguro para todos.

Blocked By Cloudflare

How Do I Know If I Have Been Blocked by Cloudflare? 

If you suspect that you’ve been blocked by Cloudflare, there are several indicators to consider:

  • Access Denied Page: If you encounter an “Access Denied” message when trying to access a website, it could indicate that Cloudflare has blocked your access.
  • CAPTCHA Desafios: Cloudflare may present CAPTCHA challenges to users if it detects suspicious behavior or potential threats. If you repeatedly encounter CAPTCHAs when accessing a website, it could suggest that Cloudflare is actively monitoring and potentially blocking your access.
  • Ray ID: Cloudflare often displays a “Ray ID” along with error messages. This unique identifier helps Cloudflare support teams identify and troubleshoot issues. If you see a Ray ID along with an error message, it indicates that Cloudflare is involved in managing the website’s traffic.
  • Screenshot Erros: Taking a screenshot of the error message or page can provide visual evidence of the Cloudflare block, which can be useful for troubleshooting and support purposes. 
IP Blocking

How Does Cloudflare Block Websites? 

Cloudflare employs various mechanisms to block access to websites for specific users or IP addresses:

  • IP Blocking: Cloudflare can block access based on IP addresses associated with malicious activity, spam, or other threats. This proactive approach helps mitigate security risks and protect websites from potential attacks.
  • Firewall Rules: Cloudflare’s Firewall Rules allow site owners to create custom rulesets to block or challenge traffic based on specific criteria, such as IP address, country of origin, or user agent. This granular control enables site owners to tailor their security policies to their specific needs and threat landscape. 
  • Challenge Mechanisms: Cloudflare may present CAPTCHA challenges, or JavaScript challenges to users to verify their identity or mitigate suspicious behavior. These challenges serve as additional layers of security to prevent automated bots and malicious actors from accessing websites. 

How Long Does a Cloudflare Block Last? 

The duration of a Cloudflare block can vary depending on the reason for the block and the actions taken by the site owner:

  • Temporary Blocks: In some cases, Cloudflare may impose temporary blocks on users or IP addresses for a specific period. These blocks are often lifted automatically after a designated time or once the triggering conditions are no longer present.
  • Permanent Blocks: In more severe cases, Cloudflare may impose permanent blocks on users or IP addresses associated with persistent malicious activity or violations of the site owner’s security policies. These blocks may require manual intervention by the site owner to lift. 

Resolution Steps: If you believe you’ve been incorrectly blocked by Cloudflare, you can reach out to the site owner or administrator for assistance. They can review the block logs, identify the reason for the block, and take appropriate actions to resolve the issue and restore access.

Lembre-se de que essas medidas estão em vigor para proteger os sites e seus usuários contra ameaças à segurança. Embora o bloqueio possa ser frustrante, a intenção é manter um ambiente on-line seguro para todos.
