You can also run `ionic serve` directly from the command line without the `npm run`. But as @Aneri points out, the application is running on port 8100. — Steven Scott, Mar 01 '18 at 16:54
@StevenScott I'm running the same but with that(ionic serve) command terminate itself and when I open localhost:8100 on browser.I'm not able to see my application whereas when I use npm run ionic:serve at that time I'm getting my Application on browser. — Aneri Vala, Mar 09 '18 at 05:58
When you go to localhost:8100 &open the debug tool (f12). What do you see in the console? — Melchia, Mar 09 '18 at 07:57
@Melchia Console is empty and on http://localhost:8100/ all I can see is this This site can’t be reached localhost refused to connect. Search Google for localhost 8100 ERR_CONNECTION_REFUSED — Aneri Vala, Mar 09 '18 at 10:22
Honestly I never saw something like this. How come the server stop without any error, unless you quit manually. — Melchia, Mar 09 '18 at 13:42
I cannot see how this fails either. Have you tried simply starting another basic project and try to see if the web server starts there? A basic template should work and be running. If that works, then simply move your pages and application into it and be running as we do not see an error stopping your server. Could you have a firewall problem? Even with npm run ionic:serve mine continues without a problem. — Steven Scott, Mar 09 '18 at 15:37

Looks like your application is already running but not getting opened in a browser tab. You can force ionic to open an application in a particular browser like:-

ionic serve -w chrome (for chrome)

ionic serve -w firefox (for mozila)

Maybe it will help.

I have seen this happen sometime when you are running ionic serve on your machine without a valid network connection. Please try when you are connected to a network.
