Ionic serve doesn't work with corporate proxy

[devsm]

Hello!
I’m new to Ionic, I’ve installed all the things and setted all the proxies but when I launch the serve command in the browser I get a “504 DNS look up failed”. How can I resolve?

I’m working on Ionic 3

Talk to you network person on how you should configure things.

They solved! Thanks!!

Can you share what the solution was? Maybe someone else will benefit from it in the future. Thanks.

For windows:
In the proxy settings where you set port and url, below in the exception sites i put “localhost”
