When your shop is giving a 413 Request Entity Too Large error, the data send to the server in a POST request is larger than the max allowed body size in Nginx.

To solve this issue create a Nginx include file as /data/web/nginx/server.bodysize and set the following setting:

The default in our Nginx configuration is set to client_max_body_size 120m; but you can easily override this value yourself in case of bigger sizes of POST data.

Keep in mind that changing this setting to a higher value can increase memory usage on the server. Don’t change this value on smaller Hypernodes (Start and Grow) as it can easily make your shop run out of resources when under attack or in case of high load.
