sockjs-node/info? 404 (Not Found)

I've done lost of search for couple of hours now and still can't find what I'm looking for. Basically I get this error in the console when running ng serve in my Angular 6 app:

GET http://local.mywebsitesecure.com/sockjs-node/info?t=1540568455931 404 (Not Found)

Based on my research the solution could be just updating

webpack.config.js

However, I can't find webpack.config.js in my project. They also say to do:

"ng eject"

to create a webpack, but it doesn't seem to work.

SOLUTION: Many people say to run this (It actually works!):

ng serve --public-host=http://localhost:4200

BUT I want to be able to set this up somewhere in my app so that I can only do

ng serve

Does anyone know how to fix this issue and gid rid of this error (sockjs-node/info). Thanks a lot in advance!
