What is Nginx Request Entity Too Large?

Nginx Request Entity Too Large refer to a type of error that occurs when an application server receives a request object larger than its maximum allowable size. This error can occur when an application server attempts to process a file or query that exceeds its preset limit. When encountering this error, Nginx will return a 413 error code, which means that the request entity is too large. In order for the request to be accepted, the size of the file or query must be reduced.

In order for your application server to understand what is happening, Nginx offers specific logging of these errors which assists in pinpointing the cause of the problem. Understanding the root cause of these errors is key in developing an effective response. In some cases, the problem may be due to a limitation of the application server itself, therefore making adjustments to the server size, as well as the code inside the application is required.

What Causes Nginx Request Entity Too Large?

In many cases, the error is caused by a limitation of the application server itself. For example, some servers may only support requests of a certain size, and requests larger than the limit will fail with a 413 error code. Additionally, the server may have an incorrect configuration that leads to the request being rejected due to its size.

Another common cause of this error is when an application attempts to handle very large files. This can happen when an application is unable to parse a large file before it attempts to process it, or when the request body is sent too large for the application server to process. Additionally, when applications are configured to accept large file uploads, they can fail if the request body is too large.

How to Diagnose the Error?

In order to diagnose this error, the first step is to identify which request is causing the problem. Nginx offers a number of helpful tools that can assist with this process. First, logging can be enabled which will provide the error code. This can then be used to view the request details, headers and body information to identify which requests are causing the error.

From there, adjustments can be made in either the configuration of the application server, or to the size of the files being requested. In some cases, a code change may be required. In general, responding to the error message by making the correct modifications to the code or configuration will resolve this issue.

Tips for Resolving the Error

It is important to remember that Nginx Request Entity Too Large errors are a sign of a problem that must be addressed. In many cases, the root cause can be easily identified and resolved. For example, if the problem is related to the application server configuration, then making sure that the correct settings are applied may resolve the issue. Additionally, if the issue is related to an application requesting a file that exceeds its preset size limit, then making adjustments to the code may be necessary.

When attempting to resolve this error, it is important to ensure that no data is lost in the process. Additionally, testing should always be done after making changes to ensure that the issue is fully addressed.


Nginx Request Entity Too Large errors can be a frustrating issue to face, but with the right approach, it can be easily resolved. It is important to understand both the cause and possible solutions for the error in order to successfully address the problem. Remember to always make sure that no data is lost when making changes to the code or configurations, and always test after making changes to ensure the issue has been effectively addressed.
