Record: nailing enterprise internal application dd.httpRequest report errors error:12

Error: the emulator on the PC can be accessed normally, but after it is released online, it will be prompted that error:12 Network error
the company requires the development of nailing add in program, I choose the enterprise internal program, the background is Java, the front end is e application
because I have intranet penetration, so I use it locally!
Both the background and the front end download the demo directly from the official website,
in the index.js The path of a URL in is domain + ‘/ Login’

let domain = "	http://sellzys.natapp4.cc";
let url = domain + '/login';

But in dd.httpRequest In the call of

dd.httpRequest({
                    url: url,
                    method: 'POST',
                    data:{
                      authCode:res.authCode
                    },

Cannot write URL
need to write directly

dd.httpRequest({
                    url: 'http://sellzys.natapp4.cc/login',
                    method: 'POST',
                    data:{
                      authCode:res.authCode
                    },

I don’t know the specific reason. I just changed the URL to a path and passed it
