Resolved: How Do I Fix Error Code 1015 Cloudflare Rate Limited

If you have ever encountered the Cloudflare error 1015, you may have wondered what it means and how to fix it. This error occurs when you are trying to access a website that is protected by Cloudflare, a service that provides security and performance optimization for websites.

Cloudflare has a feature called rate limiting, which allows website owners to limit the number of requests that a visitor can make in a certain period of time. This is done to prevent malicious attacks, such as denial-of-service (DoS) attacks, that can overload the website and affect its functionality.


However, sometimes rate limiting can also affect legitimate visitors, who may see the error message “You are being rate limited (Error 1015)” when they try to access the website. This can be frustrating and confusing, especially if you are not doing anything wrong. In this article, we will explain why Cloudflare error 1015 happens and how to fix it.

What Causes Cloudflare Error 1015?

Cloudflare sits between the visitor and the origin web server, acting as a reverse proxy. When a visitor makes a request, Cloudflare passes it to the origin server and returns the response. Error 1015 occurs when the response from the origin server is invalid or malformed, preventing Cloudflare from caching and serving it properly.

Possible Causes:

  • Origin server is overloaded, crashing, or offline
  • Origin web server configuration issue
  • Origin server script or plugin conflict
  • Denial of service (DoS) attack overwhelming the origin

How to Fix Cloudflare Error 1015

There are several possible ways to fix Cloudflare error 1015, depending on the cause and the action of the rate limit. Here are some of the common solutions that you can try:

Check Server Status

Verify the server is online and not overloaded through monitoring tools. Restart services if needed.

Identify Source of Requests

Trace traffic patterns to locate any bots, scripts or software that may be over-submitting unintended requests.

Implement Cache Validation

Use cache expiration headers to avoid unneeded requests re-validating cache on each page load.

Origin Configuration

Confirm origin allows adequate but secure RPS thresholds and can handle traffic loads without rate limiting response times.

Throttle Request Flow

Space out requests using delays or quotas to stay below enforced RPS ceiling.

Rotate Proxies Regularly

Switching IP addresses prevents any one from reaching threshold. Reliable proxy services ensure uptime.

Validate Cache Headers

Avoid reloading cached pages unnecessarily to minimize unnecessary RPS consumption.

Raise Limit Thresholds

Reduce limits if too low for regular usage to bypass error.

Remove Old Restrictions

Delete outdated configuration if rate limiting showing as disabled.

Optimize Assets

Reducing page load size through asset compression lowers resource usage.

Consider Cloudflare Plans

Higher tiers offer increased capacity for high traffic websites.

Consider Traffic Volume

Contact support if volume regularly triggers error for adjusted settings.

Web Server Configuration

Check for issues like missing dependencies, permissions errors or outdated scripts impacting responses.

Application Code & Plugins

Review application code and plugins for conflicts causing malformed responses. Deactivate non-essential components.

Denial of Service Protection

Evaluate DoS/DDoS protection like rate limiting, blacklisting or WAF rules if attacks are suspected of overwhelming backend.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions related to Cloudflare error 1015:

Question: How do I know if I am being rate limited by Cloudflare?

Answer: You can know if you are being rate limited by Cloudflare by looking at the error message that you see when you try to access the website. If you see the error 1015 message and the action that the website owner has chosen, such as challenge, block, or simulate, then you are being rate limited by Cloudflare.

Question: How long does Cloudflare error 1015 last?

Answer: The duration of Cloudflare error 1015 depends on the time interval that the website owner has set for their rate limit. For example, if the website owner has set a rate limit of 100 requests per minute, then you may see the error 1015 message for up to one minute after you trigger the rate limit. However, if you continue to make requests to the website after the time interval expires, you may trigger the rate limit again and see the error 1015 message again.
