Cloudflare is one of the most popular tools used to protect websites and ensure they stay online in case of a DDoS attack. This means implementing rules and managing traffic flow to your website so your backend server can handle. 

However, just like everything tech, Cloudflare isn’t immune to random bugs and errors or even user mistakes. In this article, we’re looking at Cloudflare error 1015, its causes and what you can do to fix the problem.

What does Cloudflare Error 1015 mean?

CloudFlare’s error 1015 means that you’re being rate limited by the website you’re trying to access. Sometimes, frequent repetitive actions can trigger the error on a protected website and block you from accessing it for a set period. 

However, the error can also indicate a broader issue with the site, like incorrect Cloudflare configurations or a general issue with Cloudflare itself.

How to fix Cloudflare error 1015?

Here are x solutions you can try out to fix error 1015.

Slow down user activity

The first step to resolving errors like this is to slow the users down. The error is caused by the user performing far too many actions in a short time. If you’re visiting a site and seeing this error, stop interacting with the site for some time, and you should be able to access it again. 

Disable rate limiting

While disabling rate limiting isn’t recommended as it leaves you open to DDoS attacks and general slowdowns caused by heavy traffic, this will allow an IP (or user) trying to access your site to do so without any problems. It would help if you used this as a temporary method in case the error 1015 is hampering your website’s user experience. 

Delete rate limiting configurations

If you’re still getting error 1015 even after disabling rate limiting, you will have to delete your old rate limiting configurations. In some cases, rate-limiting continues to work even after the setting has been disabled if the rate-limiting rules aren’t deleted. 

Increase the rate-limiting threshold

A rather low rate-limiting limit can also trigger the error 1015 unnecessarily. If you’ve set the threshold too low, even regular actions on the site can trigger this error. The simplest way to counter this is to raise the threshold to a higher number allowing for greater tolerance for repetitive actions. Alternatively, you can also just disable the limit altogether. 

Reduce the time restrictions 

Another setting you can change to eliminate error 1015 is to reduce the time it takes for the server to block a suspicious user. After rate limiting is enabled, there’s a set amount of time before a user can access the site again. If you reduce this time restriction, the error will go away quicker for the end-user.

Optimise your website

Another reason a user might have too many requests coming in from your site is the lack of optimisation. Using cookies or similar technologies, you can reduce how much data a user has to pull from the site on each visit, reducing the number of requests and the possibility of a 1015 error.

Consider a bandwidth upgrade

If your website is growing at a fast rate, you can overwhelm the bandwidth limits set by Cloudflare on your particular protection plan. Getting a plan upgrade with a greater bandwidth can help you get around error 1015.

Contact Cloudflare support

If nothing else works, the best option is to contact Cloudflare support and have them fix the problem for you. Alternatively, you can ask a question on Cloudflare’s community forum to see if someone experienced the same problems as you before and the steps they took to fix them.
