413 Request Entity Too Large nginx django

You’ve fixed the issue on your HTTP server, but your HTTP server is set to 301 redirect to your HTTPS server… your HTTPS server does not have client_max_body_size configured, so it is defaulting to 1M & causing this 413 (Request Entity Too Large) error.

To fix this issue, you simply need to add client_max_body_size to BOTH the HTTP server block and the HTTPS server block, as shown in the example below:

http {
    ...
    ######################
    # HTTP server
    ######################
    server {
        ...
        listen       80;
        server_name  xxxx.net;
        client_max_body_size 100M;
        ...
    }

    ######################
    # HTTPS server
    ######################
    server {
        ...
        listen       443 default_server ssl;
        server_name  xxxx.net;
        client_max_body_size 100M;
        ...
    }
}

More info on client_max_body_size here: http://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size

Syntax: client_max_body_size size;

Default: client_max_body_size 1m;

Context: http, server, location

Sets the maximum allowed size of the client request body, specified in
the “Content-Length” request header field. If the size in a request
exceeds the configured value, the 413 (Request Entity Too Large) error
is returned to the client. Please be aware that browsers cannot
correctly display this error. Setting size to 0 disables checking of
client request body size.
