Fix Nginx 'client intended to send too large body' error

Apr 02, 2023 · 1 min read · Post a comment

If you have an Nginx server set up to handle file uploads, and a user tries to upload a file that is larger than the configured client_max_body_size directive. When this happens, Nginx logs an error message that looks something like this:

[error] 1234#0: *56789 client intended to send too large body: 123456789 bytes

Let’s resolve it.


  • nginx
  • sudo privileges


  • According to the log mentioned above, the client sent a request with a body size of 123MB, where it’s likely that nginx client_max_body_size directive has a lower value. To resolve this, we need to increase the value of client_max_body_size to be greater than 123MB.

  • You can adjust the value of the client_max_body_size directive in your Nginx configuration to allow for larger request bodies to be accepted. For example, you can increase the value to 200MB:
    server {
      listen       80;
      # Set the maximum allowed size of the client request body to 200M
      client_max_body_size 200M;
      location / {
          proxy_pass http://upstream_server;
  • Remember to reload the Nginx configuration for the changes to take effect:
    sudo systemctl reload nginx
