NGINX error 499 is a particular case of the 502 Bad Gateway Error. At Bobcares, we can handle your NGINX issues with our Server Management Services.

NGINX Error 499

The NGINX error 499 is the HTTP 499 error that occurs on Nginx. It is common on Nginx servers because it was created by Nginx. It is a “client closed request” because it occurs when the client closes the connection while the server is still processing the request. So it falls in the category of client-based error.

The error is more common on Nginx because the server software handles client connections differently than Apache. Nginx in its own thread handles each client connection. As a result, if one client connection takes a long time to process, it will not affect the other clients.

Reasons For The NGINX Error 499

Some of the possible reasons for the error are as follows:

• Browser timing out
• User canceling the request
• Request from algorithms that create issues within the site
• No response from the server, and the client has timed out

Troubleshooting NGINX Error 499

In this section, we will provide four methods to fix the error:

1. Clear the Browser’s Cache and Retry: The method to clear the browser cache will vary depending on the browser. Clearing the browser cache and reloading the site after some time is a good solution to fix the error.

2. With the help of an APM tool: We can use APM tools to identify and troubleshoot the errors on the site, including error 499.

3. Request a timeout increase from the provider: If we have a busy website or scripts that require longer execution times, we may experience timeouts. As a result, it may be necessary to increase the timeout value. So we must contact the web host and request a timeout increase.

4. Make use of the error logs: By checking the error logs, it is easier to isolate the problem and determine whether NGINX error 499 is caused by a specific plugin or tool. We can also check the log files in Nginx (/var/log/nginx.error.log) and Apache (/var/log/apache2/error.log).
