Fix upload speeds when using Nginx for reverse proxy about speed-test HOT 2 CLOSED

I tested your configuration, It shows invalid for me.

server {

        listen 80;
       
 
       
        location / {

             
                client_max_body_size 10000M;

                proxy_pass          http://localhost:3000/;
             

        }

  }

I proxy pass with this bock of code on my machine.
to a localhost 3000, download and upload worked fine.
I think you need to fix your Nginx config.
