The server localhost:8100 is running but This adress doesn't work?

I create my ionic project with :
=> ionic start test blank
Than I start my app with :
=> ionic serve

I got this :

When i tape this adress in the browser nothing happen and I got error connection refused and the app not show.

Please help me to solve this problem , Thanks in advance

your error is correct. If you get prompt like yours E:\Ionic\Test\test, then your server is not running anymore.

Maybe you have stopped the server for example ctrl +c
Maybe something you didn’t show stopped the server.
Maybe something needs internet connection and stopped serving
