Setting Up a Reverse Proxy (Nginx) for Bambuddy

[admin]

If you want to access Bambuddy over HTTPS or via a domain name, you'll need a reverse proxy. Here's a working Nginx configuration.

Nginx Configuration

server {
    listen 80;
    server_name bambuddy.yourdomain.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name bambuddy.yourdomain.com;

    ssl_certificate /etc/letsencrypt/live/bambuddy.yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/bambuddy.yourdomain.com/privkey.pem;

    client_max_body_size 500M;
    proxy_read_timeout 300;
    proxy_connect_timeout 300;
    proxy_send_timeout 300;

    location / {
        proxy_pass http://127.0.0.1:5000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        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;
    }
}

Important Notes

• WebSocket support is required — The Upgrade and Connection headers are essential for real-time printer status updates and camera streaming.
• Increase client_max_body_size — 3MF files can be large. 500M is a safe value for print farms.
• Increase timeouts — Some operations (firmware updates, large uploads) take time.

SSL Certificate with Let's Encrypt

sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx -d bambuddy.yourdomain.com
