How can I troubleshoot connection issues when using cloudflared with my Minecraft server?

Common issues include incorrect DNS settings (ensure the A record is proxied), firewall restrictions blocking cloudflared's traffic, and incorrect cloudflared configuration. Check cloudflared's logs for errors. Also, verify your Minecraft server is binding to 127.0.0.1 and not a public IP. Use `ping mc.example.com` to confirm DNS resolution.
