Kube-apiserver default port range

I want to change the nodePort range of K8s and modify the startup parameters of kube-apiserver.
however, when I added this parameter, I found that the api would not work as long as the port range was not 30000-32768.

I have another environment, the configuration is almost exactly the same, except for the value of the IP address, it is also valid to modify this parameter.

what may be the problem and how should I find it?
