====== Cloudflared Container Name Resolution ======

**DEPRECATED:** This troubleshooting guide is no longer relevant for folk.zone. The nitro server uses direct HTTPS via Let's Encrypt instead of Cloudflare tunnels.

Cloudflared cannot resolve Docker container names.

===== Symptom =====

Services not accessible via Cloudflare tunnel. cloudflared logs show connection errors.

===== Cause =====

Cloudflared is running as a system service on the host instead of in Docker. When running as a system service, it cannot resolve Docker container names like `caddy:80`.

===== Fix =====

Run cloudflared in Docker on the same network as other services.

**Configuration:**
```yaml
services:
  cloudflared:
    image: cloudflare/cloudflared:latest
    command: tunnel --no-autoupdate run --token YOUR_TOKEN
    networks:
      - folkzone_net
```

**Steps:**
  1. Add cloudflared service to docker-compose.yml
  2. Ensure it uses the same network as other services
  3. Remove any system service installation of cloudflared
  4. Restart: `docker compose up -d cloudflared`

===== Prevention =====

Always run tunnel services in Docker alongside other services to enable proper container name resolution.
