When a visitor encounters Error 1005: Access Deniedthis usually means that Cloudflare blocked their request before it could reach the website’s server. This error can be frustrating for both users and site owners, as it often appears without clear instructions on what went wrong. Fortunately, in most cases the problem can be diagnosed and resolved with a structured troubleshooting approach. Understanding why Cloudflare triggers Error 1005 is the first step toward restoring normal access.
TL; DR: Error 1005 Access Denied happens when Cloudflare blocks a user’s IP address due to firewall rules, IP bans, geolocation restrictions, or security settings. Users can resolve this issue by disabling VPNs, clearing browser data, or switching networks. Website owners should review firewall rules, IP access lists, and security settings within Cloudflare. Proper configuration prevents legitimate visitors from being unintentionally blocked.
What is error 1005 Access Denied?
Error 1005 is a Cloudflare security restriction that prevents a customer (visitor) from accessing a website protected by Cloudflare. The message often appears as:
- Access denied
- Error code 1005
- You do not have access to this site
This error usually means that the visitor IP address is blocked by a firewall rule, IP access rule, or other security configuration set by the website owner.
Common causes of error 1005
Cloudflare uses multiple layers of protection to protect websites against bots, malicious traffic, and suspicious behavior. Error 1005 is triggered when one of these protections flags a request. The most common causes are:
- Blocked IP address in Cloudflare’s IP access rules
- Country or geolocation blocking
- Firewall rules targeting specific IP ranges
- VPN or proxy use
- Browser extensions that interfere with requests
- Temporary rate restriction
Understanding the root cause determines whether the solution should be applied by the visitor or by the site owner.
How visitors can fix error 1005
If a user encounters Error 1005, several immediate troubleshooting steps can resolve the issue.
1. Disable VPN or proxy
Many VPN services use shared IP addresses. If one user performs suspicious activity, Cloudflare can block the entire IP range. Disabling the VPN and refreshing the page often solves the problem.
2. Switch between internet networks
If the current IP address is blocked, switching from Wi-Fi to mobile data (or vice versa) can assign a new IP address and restore access.
3. Clear browser cache and cookies
Corrupted cookies or outdated cache files can trigger Cloudflare’s security checks.
- Open browser settings
- Clear browsing data
- Select cookies and cache files
- Restart the browser
4. Disable suspicious browser extensions
Ad blockers, privacy tools, or automation extensions can interfere with request headers, triggering Cloudflare’s filter. Temporarily disabling extensions can help determine the cause.
5. Contact the website owner
If none of the above solutions work, the visitor must contact the website administrator and provide the following:
- Their public IP address
- The exact error message
- The date and time of the problem
How website owners can fix error 1005
Website administrators have direct control over Cloudflare’s security features. If legitimate users report Error 1005, the problem likely stems from overly strict security settings.

1. Check IP access rules
Cloudflare allows administrators to block specific IP addresses or IP ranges. To verify:
- Log in to Cloudflare
- Select the relevant website
- Go to Security → WAF → Utilities
- View the IP access rules list
If a legitimate IP address is listed as blocked, change the setting Allow or delete the line.
2. View the firewall rules
Custom firewall rules can unintentionally block real visitors.
- Check if there are any rules that target countries or IP ranges
- Check that there are no broad expressions blocking traffic
- Temporarily disable suspicious rules for testing
Using complex expressions IP.src, country codesor threat scores can easily cause unintentional blocks.
3. Check the country block settings
Some websites deliberately restrict access from certain countries. However, if a legitimate visitor is traveling internationally, they may be blocked.
Navigate to:
- Security → WAF → Custom Rules
Check any country-specific restrictions and adjust if necessary.
4. Temporarily reduce the security level
Cloudflare’s security level (Under Attack Mode, High, Medium, Low) determines how aggressive filtering is.
Testing:
- Go to Security → Settings
- Temporarily reduce the security level
- Verify that access has been restored
If the problem goes away, you may need to fine-tune your firewall rules.
5. Disable rate limiting rules
With Rate Limiting enabled, Cloudflare can block IPs that send too many requests in a short period of time.
Account:
- Security → WAF → Speed Limit Rules
Adjust the threshold or whitelist known IP addresses.
Advanced troubleshooting
Persistent cases may require advanced diagnostics.
Check Cloudflare logs
Cloudflare logs provide detailed insight into blocked requests. By viewing logs you can identify:
- Which rule triggered the block
- Visitor’s IP address
- Country of origin
- Firewall action taken
Whitelist trusted IPs
If certain users need guaranteed access (employees or business partners), their IP addresses can be whitelisted:
- Go to Security → WAF → Utilities
- Add IP address
- Set action to Allow
Check the hosting provider settings
Although Error 1005 is Cloudflare specific, conflicts with hosting-level firewalls (such as ModSecurity) can make the problems worse. Confirm that hosting security settings do not conflict with Cloudflare policies.
Prevent error 1005 in the future
Proactive configuration reduces future disruptions.
- Avoid overly broad firewall expressions
- Test rules before full implementation
- Monitor traffic after you make security changes
- Use challenge actions instead of full blocks
Instead of blocking suspicious IPs directly, using CAPTCHA or Managed Challenge allows Cloudflare to authenticate human visitors while minimizing false positives.
Error 1005 vs. other Cloudflare errors
It is important not to confuse Error 1005 with similar Cloudflare codes:
- Error 1020: Access denied due to firewall rule violation
- Error 1015: Rate limited
- Error 1010: Browser signature prohibited
Although these errors may seem similar, Error 1005 refers specifically to IP-based access restrictions.
When should you escalate to Cloudflare support?
If administrators can’t determine which rule caused the block:
- Open a support ticket with Cloudflare
- Include Ray ID from the error page
- Provide a timestamp and the IP address involved
The Ray ID helps Cloudflare quickly trace the blocked request.
Conclusion
Error 1005 Access Denied is mainly a conflict with safety rules instead of a technical server failure. For visitors, simple steps such as disabling VPNs or switching networks often solve the problem. For administrators, checking IP access rules and firewall settings within Cloudflare is usually sufficient. With careful configuration and regular monitoring, websites can maintain strong protection without blocking legitimate users.
Frequently Asked Questions (FAQ)
1. What does Error 1005 Access Denied mean?
It means that Cloudflare has blocked your IP address based on security or firewall rules configured by the website owner.
2. Is Error 1005 caused by the website being unavailable?
No. The website is usually online, but Cloudflare is preventing your specific request from reaching it.
3. Can a VPN cause Error 1005?
Yes. Shared VPN IP addresses are often flagged or blocked, especially if they generate suspicious traffic.
4. How can I find my IP address to provide to the site owner?
You can search for ‘What is my IP’ in a search engine and your public IP address will be displayed.
5. How long does an IP blocking last?
It depends on how the rule is configured. Some blocks are temporary (rate limiting), while others are permanent until manually removed.
6. Is error 1005 the same as error 1020?
No. While both involve denying access, Error 1020 specifically indicates a firewall rule violation, while 1005 typically refers to an IP ban.
7. Can website owners prevent false positives?
Yes. They can use Managed Challenges instead of hard blocks and carefully test firewall rules before publicly activating them.
