Proxmox Reverse Proxy with Nginx

config

server {
    listen 443;
    server_name pve.mydomain.com;
    
    ssl on;
    ssl_certificate /etc/nginx/ssl/ssl.crt;
    ssl_certificate_key /etc/nginx/ssl/ssl.key;
    
    proxy_redirect off;
    location / {
    	proxy_set_header X-Forwarded-Proto https;
        proxy_pass https://10.10.10.101:8006;
        
        # Enable websockets for the noVNC console to work
        proxy_http_version 1.1;
	proxy_set_header Connection $http_connection;
	proxy_set_header Origin http://$host;
	proxy_set_header Upgrade $http_upgrade;
    }
}

AFAIK you can't do this on subdomains anyways because proxmox cookies will get confused. It didn't even work if proxmox are on different ports (8006, 8007 for example). When logged into one proxmox, other session gets destroyed.

Also as of proxmox5 the noVNC proxying via nginx is broken. It works randomly on multiple connection retries.

To prevent hangup of screen on novnc i suggest to add :

client_max_body_size 10240M;
client_body_buffer_size 4m;
proxy_connect_timeout 7d;
proxy_send_timeout 7d;
proxy_read_timeout 7d;
proxy_cache off;
