If you’re getting 413 Request Entity Too Large errors trying to upload with Nginx , you need to increase the size limit in nginx.conf . Add client_max_body_size xxM inside the server section, where xx is the size (in megabytes) that you want to allow.

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
 
    server {
        client_max_body_size 20M;
        listen       80;
        server_name  localhost;
 
        # Main location
        location / {
            proxy_pass         http://127.0.0.1:8000/;
        }
    }
}
