What are common issues when setting up Certbot with Cloudflare DNS via Docker Compose?

Common issues include incorrect Cloudflare API credentials (permissions or validity), improper mounting of volumes for certificate storage or credentials, firewall rules blocking access to Cloudflare API endpoints, incorrect DNS configuration in Cloudflare, and errors in the Certbot `entrypoint` or command arguments within the `docker-compose.yml`. Ensure your API token has the correct permissions (e.g., Zone:DNS:Edit) and that the credentials file is readable by the Certbot container.
