Why Do Some Websites Get Stuck on Cloudflare Human Verification?


If you’ve tried to access a website and got stuck on the Cloudflare screen that says “Checking if the site connection is secure…”, this issue is often due to IPv6, browser settings, or DNS issues. Here’s how to fix it!


What Causes This?

  • IPv6 misconfigured: The website or server may not handle IPv6 correctly.
  • Firewall settings: Security settings can block Cloudflare’s checks.
  • Strict bot protection: Cloudflare may mistakenly flag real visitors.
  • Browser issues: Extensions like VPNs or ad blockers may interfere.
  • DNS misconfiguration: Incorrect DNS settings can cause delays.

How to Fix It

  1. Refresh the page.
  2. Clear your browser cache and cookies.
  3. Disable VPNs, ad blockers, or script blockers.
  4. Try incognito/private mode.
  5. Use a different browser (Chrome, Firefox, Edge).
  6. Switch to mobile data or a hotspot.
  7. Change your DNS to trusted services like:
    • 8.8.8.8 (Google DNS)
    • 1.1.1.1 (Cloudflare DNS)

Why Change DNS?

Using public DNS services like Google or Cloudflare can improve website loading speeds and reliability by avoiding issues with your default DNS provider.
