Error Code 1015: Causes, Fixes, and How to Prevent It

Error Code 1015 appears when Cloudflare restricts access to a website due to suspiciously high activity. Cloudflare is a global content delivery network (CDN) and web security platform that filters traffic, caches pages, manages DNS, and protects sites from DDoS attacks. If too many requests come from a single IP address, the protection system is triggered and temporarily blocks access. This disrupts normal browsing, script execution, scraping, and similar activities.

What is error 1015 meaning and how to fix the issue depending on its cause – read below.

What Is Error 1015?

This problem is not related to internal failures of the web resource and does not depend on the user’s browser. In the context of Cloudflare, Error 1015 means an HTTP response generated by the platform when a set query limit is exceeded from a single IP address, session, or device.

With error 1015 rate limited it is defined by the site’s policies – for example, 10 calls within 5 seconds from one IP. At the same time, not only the number of attempts is recorded. Additional parameters come into play: query path, HTTP method (GET, POST, etc.), cookies, headers, and behavioral patterns. This makes it possible to distinguish between, for example, mass scraping and legitimate user actions. The blocking code is returned only in cases of suspicious activity.

Error Code 1015 vs. 429: What’s the Difference

Both issues arise from identical causes but differ in how they are handled:

• Error 429 is returned by the website server when a user makes too many requests to a resource, for example, while using an API. The response usually contains code 429 and the message “Too Many Requests”.

  

• Error 1015 occurs when the rate limit set by Cloudflare is triggered. In this case, the message “Error 1015: You are being rate limited” appears.

  

If Cloudflare is not used, error will not appear — instead, code 429 or another internal blocking mechanism will take effect.

Error Code 1015: Causes and Consequences

The platform blocks access if a user’s or program’s actions match patterns of automated behavior. Below are the main reasons for triggering protection and how this manifests in real-world scenarios.

How to Fix Error 1015: A Practical Guide

Below are typical scenarios in which protection is triggered and specific methods for resolving the issue in each case.

High Activity After Launching a Parser, Macro, or Auto-clicker

Automated queries without signs of real user interaction (mouse movements, scrolling, clicks) are classified as suspicious. Sessions with high-frequency repeated calls are blocked by the system.

How to fix it:

• Reduce calls frequency, set pauses between them of at least 1–2 seconds.
• Implement user-like behavior: cursor movement, scrolling, hovering.
• Use rotating proxies with a high level of trust and low load.
• Clear cookies and local parameters before starting automated scenarios.

These measures help avoid triggering protective filters, working within their conditions when handling large volumes of requests to a resource.

Network Failures and Session Interruptions

Error code 1015 can occur not only due to frequent requests but also from unstable internet connections. Slow Wi-Fi, connection drops, high ping, packet loss, DNS issues, or temporary ISP outages can cause page loading to pause and resume. For traffic filtering systems, this looks like suspicious activity, which may trigger blocking.

How to fix it:

• Check the stability of the connection: test ping and packet loss, as well as speed, using monitoring services.
• Switch to a more stable network or wired connection.
• Configure alternative DNS servers (e.g., Google Public DNS) to speed up domain resolution.
• Minimize background downloads and updates to avoid overloading the channel while working with the site.

Timely resolution of network issues reduces the risk of false positives from security filters and ensures stable operation even on resources with strict request rate limits.

Blocking Immediately Upon Opening the Site

If an IP address has a low reputation (e.g., previously used for spam or automation) or is actively used by other users, Cloudflare may immediately block access — even before the page loads or authorization occurs.

How to fix it:

• Change the IP address – use a private proxy with a good reputation.
• Make sure the IP is not being used in other sessions, bots, scripts, or automated services. It is recommended to close all browsers, parsers, VPNs, and disconnect other devices from the network.

If necessary, contact the site administrator with a description of the situation and a request for unblocking.

Access Denied During Authorization, Checkout, or Payment

Cloudflare may detect a conflict with authorization data (cookies, tokens) when attempting to access secure sections of a site. Repeated or outdated parameters can trigger an access error.

How to fix it:

• Clear cookies and local storage for the site.
• Open the site in incognito mode to exclude the impact of outdated authorization data.
• Use an alternative browser or device.

If the problem persists, contact the site’s support team to resolve the authorization issue.

Automation Software Not Working

When running automated scenarios (parsers, macros, auto-clickers), the system analyzes user behavior when loading the page. If there are no actions such as cursor movement, scrolling, or clicks, the session may be classified as automated and restricted.

How to fix it:

• Avoid opening pages in headless mode without visualization (e.g., through headless browsers or iframes).
• When using automation, implement actions that mimic real behavior: scrolling, mouse movements, random pauses.
• Ensure JavaScript execution is enabled in the browser, as it is required for the correct operation of protection mechanisms. This setting can usually be found in the “Privacy and Security” section.

By simulating real user behavior, the risk of blocking is reduced, ensuring stable access to the website’s functionality.

Tools and Services to Bypass Error Code 1015

To minimize the risk of encountering such an issue, it is important to understand the reasons behind it and apply the right technical solutions.

Read our previously prepared material on what rotating proxies are to better understand their role in solving error 1015.

Conclusion

Error Code 1015 is not a technical malfunction but a signal of suspicious activity. It occurs when request frequency limits are exceeded, behavioral patterns are absent, or the IP address is of low quality. This issue often arises during parsing, multi-accounting, and automation. To bypass it, it is crucial to understand the causes of restrictions and rely only on proven solutions: rotating proxies, antidetect browsers, UI emulators, etc.

For stable access even to highly protected resources using Cloudflare, it is recommended to use our residential or mobile private proxies with a high trust factor.

FAQ

Can the issue be caused by extensions or background tabs?

Yes. Browser extensions, auto-refreshing pages, or background tabs can create excessive activity and trigger a block.

How long does Error 1015 blocking last?

Usually, from a few minutes to an hour, but the exact duration depends on the system settings of the specific site. Repeated requests to the resource without behavioral changes (e.g., scripts) may extend the block.

Why does Error 1015 occur only on one Wi-Fi network?

This is usually related to the network’s IP address. If the IP has a poor reputation, was previously blacklisted, or is simultaneously used by multiple devices, the system may restrict access. Connecting via another network or mobile internet changes the IP, preventing the block.
