When you try to access a website protected by Cloudflare, you may encounter situations where bot verification cannot be passed. This article will help you understand the possible causes and provide solutions.

Possible Causes and Solutions

Proxy or VPN Tools: Using proxy servers may cause IP addresses to be flagged as suspicious, triggering stricter verification.
- Solution: Temporarily disable proxy tools or switch to a different proxy server and retry
Browser Extensions: Some browser extensions (such as ad blockers or privacy protection tools) may interfere with the verification process.
- Solution: Try disabling all extensions and re-verify, or use your browser's private mode (incognito mode)
Browser Cache and Cookie Issues: Expired or corrupted cache data may affect the verification process.
- Solution: Clear your browser's cache and cookies, then revisit the website
Outdated Browser Version: Older browser versions may have compatibility issues.
- Solution: Update your browser to the latest version
Unstable Network Connection: An unstable network connection may also cause verification to fail.
- Solution: Check network connection stability, or try switching to another network (such as mobile data or a different Wi-Fi network)

Important Notes

If you still cannot pass verification after multiple attempts, wait for a period of time (such as 30 minutes to several hours) before trying again
Accessing from public networks (such as café Wi-Fi) is more likely to trigger verification, as these IP addresses may have been used by multiple people
If the problem persists, try contacting the website administrator for further assistance
