Reverse proxy

Expose Aetheris behind Nginx or Caddy with TLS.

Nginx

server {
    listen 80;
    server_name app.example.com;
 
    location / {
        proxy_pass http://127.0.0.1:3000;
        proxy_http_version 1.1;
        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;
        # Required for VNC console WebSocket:
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_read_timeout 600s;
    }
}

sudo ln -s /etc/nginx/sites-available/aetheris /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx
sudo certbot --nginx -d app.example.com

Caddy (auto-TLS)

app.example.com {
    reverse_proxy 127.0.0.1:3000
}

Caddy automatically provisions and renews TLS certificates.

WebSocket headers

The VNC console requires Upgrade and Connection: upgrade headers. Without them the console shows no frames. Both Nginx and Caddy handle this correctly with the configs above.
