Nginx error: client intended to send too large body

Periodically I get an error:

This site can't be reached.
The webpage at https://example.com/document might be temporarily down or it my have moved permanently to are new web address.

My site is stored on AWS. I use rails + nginx + passenger.

Nginx error log:

client intended to send too large body: 3729822 bytes, 
client: 172.42.35.54, server: example.com, 
request: "POST /document HTTP/1.1", host: "test.example.com", 
referrer: "https://test.example.com/document/new"

app log:

ActionController::RoutingError (No route matches [GET] "/document")

After a while, the error disappears. I have doubts that this is due to deployment, but I'm not sure. Could you please tell me, with what it can be related and how to fix such a problem?

I have updated /etc/nginx/nginx.conf

in my case, I have added client_max_body_size in http block after sendfile on; as below

http {
    ...
    sendfile on;
    client_max_body_size 20M;
}

it is very important to put client_max_body_size after sendfile on;

Don't forget to restart nginx as below after updating the nginx.conf

For ubuntu

sudo service nginx restart

For Centos

sudo systemctl restart nginx

Add the following 3 commands inside the server clause of the nginx.conf

    sendfile on;
    client_max_body_size 20M;
    client_body_buffer_size 20M;

For me path of nginx.conf was /etc/nginx/nginx.conf.

In my case I just added client_max_body_size in http block and it worked for me

http {
    ...
    client_max_body_size 20M;
}

Make sure to restart nginx after changing this config

Default Nginx config limits client request body with 1Mb.
You have to increase client_max_body_size to allow users to post large documents.
Don't miss with the context (http, server, location) of this derictive and don't forget to reload configuration or restart Nginx after that.
