2674	Unable to set `proxy_max_temp_file_size` greater than 1024m	PyroGenesis@…		"I am using NGINX on Windows as a reverse proxy to a library endpoint. I want to increase the value in the `proxy_max_temp_file_size` directive to serve some of my larger libraries.

However, setting `proxy_max_temp_file_size` to a value above 1024m gives me the following error:
```
nginx: [emerg] ""proxy_max_temp_file_size"" directive invalid value in path/to/nginx.conf:178
```

Here is the full nginx.conf
```nginx
#user  nobody;
worker_processes 2;

events {
    worker_connections 1024;
}

http {
    include mime.types;
    default_type application/octet-stream;

    sendfile on;
    keepalive_timeout 65;

    # upstream endpoint
    upstream pypi-gpu {
        server localhost:9500;
    }

    server {
        listen 9000 ssl;
        server_name pythonlibs.mydomain.com;

        ssl_certificate ""path/to/cert.crt"";
        ssl_certificate_key ""path/to/private.key"";
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers HIGH:!aNULL:!MD5;

        location / {
            proxy_max_temp_file_size 3072m;
            proxy_set_header Host $host:$server_port;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_pass http://pypi-gpu;
        }
    }
}
```

Note that setting `proxy_max_temp_file_size 0` allows me to serve large files but I'd prefer to keep this bounded if possible.
