Cordova Whitelist plugin not working on mobile browser


I used Ionic 1 to build a web app instead of a native app. I deployed the web application and try to access it using mobile devices. I found all the Http requests made by the app are blocked, which shows “POST url net::ERR_NAME_NOT_RESOLVED”.
It works fine when I use the desktop to access the web application, so I think it is related to the Whitelist plugin.
But it still doesn’t work after I applied the Whitelist plugin

Is the Whitelist plugin only works when it is compiled and run as a native app?

Could someone help me?
