This seems like an issue with your Apache2 server rather than NPM.

How to use it，Could you tell me how to do it in detail?

i realized that you have to use the ip of the container. For example 172.19.0.2:81

For reference: I had this issue on Unraid and the fix was to enable Host access to custom networks in Settings > Docker > Advanced View.
