Ionic Serve, port?

Ionic Framework
1

HI,

Is it possible to change the port, where the App will run, when we type ionic serve?

2

The CLI is completely documented, check it out here: ionic serve: Start a Local Development Server for App Dev/Testing

There is a --port option

Thanks

I am getting the following error

“Invalid Host header”

I am not sure if this is related?
