Can't reach localhost in node-red with http request node

i have a web services URLs that starts with http://localhost:8001/clients. i have tried to put it in http request node but it always get statusCode: 401 ( unauthorised).
but when i type in chrome http://localhost:8001/clients it works an get me the reponse body.
Any help will be appreciated.

What security have you got setup on the web service? Your browser may already have a valid cookie or caches session that allows it to access the url.

WS is configured for Windows credential type, i think that's why it only works on chrome..
