namefi-https-and-routing

Use when putting a reverse proxy in front of locally-developed services so a domain serves real HTTPS - getting a Let's Encrypt or ZeroSSL certificate for a home or VPS service, routing several apps behind one public IP and one port 443 by Host header, choosing between Caddy and Traefik, debugging ACME HTTP-01/TLS-ALPN-01/DNS-01 failures, wildcard certificates, "serve my local app over https on my domain", or "connection refused from outside but works inside".
