I already configured dns to point to the domain and hosting, but the problem is that it can’t access other ports, but can access the default port normally.
Cloudflare only supports HTTP/HTTPS on certain ports on hostnames that are Proxied . Port 4500 is not a supported port.
You can change the hostname to DNS Only , or use a separate hostname that is if your normal website is on the same hostname.
Cloudflare Spectrum is also an option, but only relevant if you are an Enterprise Customer.
