How can I troubleshoot issues with the Cloudflare Speed Test integration in OpenWrt?

Troubleshooting can involve checking several areas. First, verify the Cloudflare API key is valid and hasn't been revoked. Examine the script's logs for errors. Test the script manually using `curl` or a similar tool to isolate the problem. Ensure that the OpenWrt system has network connectivity to Cloudflare's servers. Check for any firewall rules that might be blocking access to the API. Debugging Lua scripts can be challenging; use `print` statements strategically to trace the execution flow. Finally, review Cloudflare's API documentation for any changes or issues.
