and this my nginx config

server {
  listen 80;
  listen 443 ssl http2;
  ssl_certificate /home/justdev/ssl/just-car/cert.pem;
  ssl_certificate_key /home/justdev/ssl/just-car/key.pem;

  client_max_body_size 16g;
  proxy_read_timeout 900;
  server_name example.example.com;

  location /portainer/ {
    proxy_pass http://localhost:9000/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_buffering off;
    client_max_body_size 0;
  }

  location /registry/ {
    proxy_pass http://localhost:5000/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;

  }

  location /v2/ {

}

I want to be able to push my image into my private docker registry

removing proxy_buffering off; should fix the issue. like:

location /v2/ {
    proxy_pass http://localhost:5000/v2/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    client_max_body_size 6G;
}
