webpack sockjs-node Not receiving --host option

[Dav0n]

During a nodejs webpack development
npm run serve -- --host x.x.x.x --port 9999
sockjs is not getting the parameter but for port it will do
from firefox console ->> http://localhost:9999/sockjs-node/info?t=1561647376841

I've found that in file "node_modules\webpack-dev-server\client\index.js" while running in client:
line 226:
var hostname = urlParts.hostname; <- first time evaluate to localhost, later to the right url value
var protocol = urlParts.protocol;
var port = urlParts.port; // check ipv4 and ipv6 all hostname

May be this isn't the right thread
