How to fix NGINX client prematurely closed stream error?

Question

Nginx

Hello, when uploading files, I get an error:

*1517 client prematurely closed stream: only 288266169 out of 288266873 bytes of request body received, client: 1.1.1.1, server: example.org, request: "POST /bla/bla HTTP/2.0", host: "example.org", referrer: "https://example.org

"
Config:

client_body_temp_path  /tmp/;
client_body_in_file_only clean;
client_body_buffer_size 1m;
client_max_body_size 30000m;
client_header_timeout 10000s;
client_body_timeout 10000s;
keepalive_timeout 10000s;
proxy_ignore_client_abort on;
proxy_buffering off;
proxy_connect_timeout 6000s;
proxy_send_timeout   6000s;
proxy_read_timeout   6000s;
proxy_buffer_size    64k;
proxy_buffers     16 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;

What is the root of the problem, can upstream be to blame?
But when I check the /tmp folder for upstream, it does not clog when the file is uploaded

This is not a server error, but they write to you in human language - the client did not take the file to the end. It needs to be diagnosed from the other side. Maybe the internet is unstable or something...
