413 Request Entity Too Large nginx django

Question

I am making a practice web service (client's artbook display web site) The client can upload artbook images to the server.

But I get the following error when the client uploads too many images

413 Request Entity Too Large

I tried adding client_max_body_size 100M; in nginx.conf

#user  nobody;
#Defines which Linux system user will own and run the Nginx server

worker_processes  1;

#error_log  logs/error.log; #error_log  logs/error.log  notice;
#Specifies the file where server logs.

#pid        logs/nginx.pid;
#nginx will write its master process ID(PID).

events {
    worker_connections  1024;
}


http {
    include       mime.types;

    default_type  application/octet-stream;

    #access_log  logs/access.log  main;

    sendfile        on;

    server {
        listen       80;

        server_name  xxxx.net;
        client_max_body_size 100M;
        keepalive_timeout 5;

        return 301 https://$server_name$request_uri;

    }

    # HTTPS server
    #
    server {
        listen       443 default_server ssl;
        server_name  xxx.net;

        ssl_certificate      /etc/letsencrypt/live/xxxx.net/fullchain.pem;
        ssl_certificate_key  /etc/letsencrypt/live/xxxx.net/privkey.pem;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;


        location / {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto https;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header HOST $http_host;
            proxy_set_header X-NginX-Proxy true;

            proxy_pass http://127.0.0.1:8000;
            proxy_redirect off;
        }
    }
}

and tried:

sudo service nginx restart
sudo service nginx reload

and retry

runserver

but still get

413 Request Entity Too Large

Can anybody help?

Is nginx running on its own or is there some other platform (PHP, Python etc) that it is proxying for? — solarissmoke, May 03 '16 at 04:06
Also you have added `client_max_body_size` to your HTTP server block but not to the HTTPS server block. That is probably where the issue is. — solarissmoke, May 03 '16 at 04:56
I solved my problem, HTTPS **must have client_max_body_size** thank you @solarissmoke — Jade Han, May 04 '16 at 04:21

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.

Thanks, this was helpful. After making the changes, I ran sudo service nginx restart sudo service nginx reload — JayB, May 09 '23 at 23:24

Open the terminal for Ubuntu

Use nano text editor:

$

sudo nano /etc/nginx/nginx.conf

set client body size to 100M

client_max_body_size 100M;

Like:

http {

        ##
        # Basic Settings
        ##
        client_max_body_size 100M;
        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        # server_tokens off;

        # server_names_hash_bucket_size 64;
        # server_name_in_redirect off;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        ##
        # SSL Settings
        ## More codes here ...

}

I know this has already been answered, but rather than having the "client_max_body_size 100M;" multiple times in your code under the servers, you can just add it once, under the http section - see line 2 below.

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

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