Troubleshooting common issues with Cloudflare Tunnel and Home Assistant Docker

Common issues include incorrect tunnel configuration (e.g., wrong tunnel ID), firewall rules blocking traffic, incorrect port mappings in the `config.yml` file, or DNS propagation delays. Check Cloudflare's logs for errors, verify your Home Assistant configuration, and ensure your firewall allows traffic to the Cloudflare Tunnel's IP addresses. Also, ensure the container's network settings are configured correctly to communicate with the tunnel.
