Host not configured in Nginx Proxy Manager

Your request reached the proxy, but no Proxy Host matches this hostname.

Requested Host unknown protocol

How to fix

  1. Create a Proxy Host in NPM with this exact domain name.
  2. Point it to your backend service’s IP and port (scheme http/https correctly).
  3. Attach your SSL certificate (wildcard or apex) and enable Force SSL if desired.
  4. Ensure your local DNS resolves this domain to the NPM IP.

Show tips
  • The Proxy Host must include exactly this domain (no extra spaces, no missing labels).
  • In Pi-hole, ensure the domain resolves to your NPM IP (e.g., 192.168.0.101).
  • If your backend uses HTTPS with a self-signed cert, enable “Ignore invalid SSL” in NPM.
  • For remote access, forward TCP 80/443 to NPM; for LAN-only with DNS-01, no ports are needed.
