We have a fairly complex nginx config however the vhost that I know I am having issues is quiet simple.

We have  aio threads ; enabled 


/usr/sbin/nginx -V
nginx version: nginx/1.19.6

        ssl_dhparam /etc/nginx/dhparams.pem ;

        proxy_http_version 1.1;
        proxy_headers_hash_bucket_size 4096 ;
        proxy_set_header Connection "";
        client_max_body_size 4G;
        keepalive_timeout 5;
        server_name media.archiveofourown.org media.transformativeworks.org ;
        root /var/www/media;

        location / {
                access_log off;
                autoindex on;
        }

}

When I try and download a larger than average file It fails, it fails in the same way if I try and us the internal ip address and port directly rather than via the haproxy ( firewall ) etc. I believe the issue does occur with more than just large downloads.
