The 413 Request Entity Too Large error is a common error that occurs when a client tries to send a request to an nginx server that is larger than the maximum file upload size that is configured for the server.
Here’s what the error might look like:
To fix the 413 Request Entity Too Large error in nginx, you need to increase the maximum file upload size that is configured for the server. The default maximum file upload size for nginx is 1 megabyte. You can increase the maximum file upload size by editing the nginx configuration file.
You can increase the maximum file upload size by adding or updating the following property in nginx server configuration file. Be sure to replace “100m” with a value that’s bigger than the file that you’re trying to upload. The value can be specified in various units, such as “k” for kilobytes, “m” for megabytes, and “g” for gigabytes.
Here’s what your configuration may look like after adding “client_max_body_size” property.
Once you have updated
client_max_body_size , the maximum file upload size for your nginx server will be increased to the value that you specified. This will prevent the 413 Request Entity Too Large error from occurring when clients try to send requests that are larger than the maximum file upload size.
Here are some additional things to keep in mind when increasing the maximum file upload size in nginx:
client_max_body_sizedirective only applies to POST requests.
client_max_body_sizedirective is applied after the
client_body_buffer_sizedirective. This means that if the client request body size exceeds the value of the
client_body_buffer_sizedirective, nginx will still accept the request, but it will only store the first
client_body_buffer_sizebytes in memory.
client_max_body_sizedirective can be overridden by the
client_max_body_sizedirective in a location block.
