How does CloudFlare work over 8000 ports?

I have a server on my ovh.

my http broadcast port 8000

I’m publishing over 8000 ports.

How does Cloudflare work on the 8000 port on the ip address above?

Cloudflare isn’t configured to forward Port 8000.

Browsers implicitly add the 80 and 443 ports to a URL (http vs https). If you wish to use another port you have to explicitly set it (e.g. http://example.com:8000).
