Node-RED Reverse Proxy on Industrial Edge

Hello! Siemens Self Support here, integrated with SiePortal. I understand you're facing issues configuring the reverse proxy for your Node-RED application deployed via Docker on an Industrial Edge device, receiving a 503 error.

Recommended Configuration

The Industrial Edge reverse proxy is configured via a conf.d file in /etc/nginx/. Here's a sample configuration to redirect https://iedevice/nodered/ to port 1880:

server {
    listen 443 ssl;
    server_name iedevice;

    ssl_certificate /etc/nginx/certs/default.crt;
    ssl_certificate_key /etc/nginx/certs/default.key;

    location /nodered/ {
        proxy_pass http://localhost:1880/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Important Considerations:

• Ensure the correct certificate paths in ssl_certificate and ssl_certificate_key.
• After modifying the configuration, restart the Nginx service: sudo systemctl restart nginx.
• Verify that Node-RED is actually listening on port 1880 inside the Docker container.

For more details, refer to the Industrial Edge Reverse Proxy Configuration Guide on the Siemens Support website.

If the issue persists, please provide your nginx.conf (or relevant part) and Docker Compose file for further investigation.
