Open ports cloudflare

Need assistance on these open ports by default on Cloudflare - 2053, 2083, 2087, 2096, 8443.

Can I close these ports? Need guidance on the proper commands on how to close these ports. And let me know if it’s possible and won’t have any issues after closing it.

You cannot close the ports, but you can deploy a WAF rule to block all requests to the ports. Instructions on the link below.

If you are being required by an auditor or similar to tick a box, you will have to explain to them that no traffic can be passed to your Origin on those ports (once you have the WAF rule in place) and that there is no risk associated with the ports being open.
