Nginx Error – 413 Request Entity Too Large Fix

If you’re getting 413 Request Entity Too Large errors trying to upload files to your webserver, you need to increase the client body size limit in your nginx.conf configuration file.

Add ‘client_max_body_size xxM’ inside the server section, where xx is the size (in MB) that you want to allow for files upload to your webserver.

The client_max_body_size directive assigns the maximum accepted body size of client request, indicated by the line Content-Length in the header of request.

To edit your nginx configuration, in your terminal type the following:

sudo nano /etc/nginx/nginx.conf
or
sudo nano /usr/local/nginx/conf/nginx.conf
and set the
# set client body size to 2M #
client_max_body_size 2M;

as per the example below:

http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;

server {
client_max_body_size 2M;
listen 80;
server_name localhost;

# Main location
location / {
proxy_pass http://127.0.0.1:8000/;
}
}
}
