.Net core and React uppy.io 110mb file upload exception "Unexpected end of request content."

Question

I have a Asp.net core 3.1 api and react typescript application.

When large file uploaded then i get exception this error

"Unexpected end of request content."

React component is Uppy.io and upload method is XHR

I use nginx for request receive

I tried below solutions

nginx large file settings client_max_body_size 2000M;
Asp.net Core file settings options.Limits.MaxRequestBodySize = long.MaxValue;

But not work

I tried 20mb file to slowing down the browser for determine the problem. It is work. In my opinion problem is not long upload time.

I tested on 110 mb file

Uppy.io component is progress 100 then waiting 30 second and throw exception

Is the app running in an environment with limited RAM? You might be getting an OOM error somewhere — abdusco, Jul 13 '21 at 08:08
@abdusco I checked server. It is vm and 7gb ram available. Application created with kestrel service not docker. — ismail ERDEN, Jul 13 '21 at 08:48
Are there any reverse proxies in front of nginx? A firewall perhaps? They might be dropping the connection once the request size exceeds a certain size. Check the browser console. Does anything strange happen when the upload stops? — abdusco, Jul 13 '21 at 09:10

I solved to my problem.

I Added on below code on nginx location block.

It's Work

proxy_http_version 1.1;
proxy_set_header Connection keep-alive;
client_max_body_size 2000M;
proxy_request_buffering off;
proxy_send_timeout 1h;
proxy_read_timeout 1h;

Asp.net added to below code

services.Configure<FormOptions>(x =>
            {
                x.ValueLengthLimit = int.MaxValue;
                x.MultipartBodyLengthLimit = int.MaxValue; 
            });
