Cloudflare is a popular content delivery network that provides security and performance-enhancing services to websites across the globe. However, like any other online platform, it is also prone to occasional errors, which can hinder the user experience of visitors to your site.
One such error is the Cloudflare error 499 “client closed request,” which occurs when the client closes the connection while the server is still processing the request. In this article, we will provide you with troubleshooting tips to fix this error.
At WordaTheme, we understand that website errors can be frustrating, and that is why our team of experts is dedicated to providing server management services to clients worldwide. Our experience with Cloudflare has equipped us with the knowledge and expertise to offer solutions to every query that comes our way.
Understanding Cloudflare Error 499 “Client Closed Request”
Cloudflare error 499 “client closed request” occurs when the server is unable to provide a status code back after the client closes the connection while the server is still processing the request. Since NGINX was used to build Cloudflare, we also have a 499 HTTP code in ELS and statistics for connections that disconnect before the request processing is complete. Clients closing connections is usual behaviour, and these errors can be seen in logs on an irregular basis.
Identifying the Reason Behind the Error
To fix the error, we must first identify the reason behind it. Here are some of the prominent reasons and corresponding solutions:
- If the application freezes, an error may occur. First, we need to instruct Nginx to wait more time. By changing the
fastcgi_read_timeout, the Nginx’s timeouts will be increased. If waiting longer does not fix the issue, we can also increase the server’s processing power.
- A “hang” or “code freeze” in the app or content manager may be the cause of the 499 error if it appears on a particular page or request. We should ensure the WordPress plugins are compatible and verify that tables and indexes are in good condition before running any database queries.
- If the 499 error occurs when the website is behind a proxy, we must increase the app server’s processing power. We can decrease the time Nginx users have to wait before using the service by raising “processing power.” We can also increase the timeouts of your proxies (load balancer, CDN, firewall, etc.) if you can’t boost the power of your application server.
- As the server closes the connection, we may see this error. We can increase the server’s processing power or use the
fastcgi_read_timeoutoption in Nginx to extend timeouts.
