Can't upload ISOs to my Proxmox via nginx and Cloudflare tunnel.

Hi guys.
Some time ago, I decided to have public access to manage my Proxmox server everywhere I go.

So by these I've made a Cloudflare Tunnel, installing it on may Proxmox server and configuring Nginx as a webmanager, because the default port 8006 has no access through the Cloudflare tunnel.

Editing the Proxmox.conf as these ay:
Code: 
nano /etc/nginx/conf.d/proxmox.conf

Code: 
  GNU nano 7.2                   /etc/nginx/conf.d/proxmox.conf                             
server {
    listen 443;
    server_name _;
    ssl on;
    ssl_certificate /etc/pve/local/pve-ssl.pem;
    ssl_certificate_key /etc/pve/local/pve-ssl.key;
    proxy_redirect off;
    location / {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_pass https://192.168.0.4:8006;
        proxy_buffering off;
        client_max_body_size 0;
        proxy_connect_timeout  3600s;
        proxy_read_timeout  3600s;
        proxy_send_timeout  3600s;
        send_timeout  3600s;
    }
}

server {
    listen       80;
    charset utf-8;
    server_name  pveserver.garciacloud.uk;
    location / {
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        include proxy_params;
        proxy_pass https://192.168.0.4:8006;

    }

}

Where:
192.168.0.4 is the local IP of my Proxmox server.


So In the Cloudflare tunnel I added a Public Hostname, pointing to: http://192.168.0.4
and It works I can get access to my Proxmox server and its VM machines.
(I'm not using https://192.168.0.4, because when I use it, server its unreachable)

But I'm noticing that I cannot Upload ISOs on my Proxmox server.
when I choose an ISO and I clicked "Upload" button, the progress bar its stopped and it doesn't work.


What am I doing wrong? :(

Thanks in Advance

Click to expand...
Reading other post I found the solution.


Just by changing the buffer of the nginx server adding these lines on Proxmox.conf:

Code: 
client_header_buffer_size 1k;
    large_client_header_buffers 2 1k;
 
I encountered the issue too. Adding this did the trick, even tho the upload is slower than without the reverse proxy

Code: 
client_max_body_size 10G;
