Ionic serve returns "Application not found" error

Hello, i’m having a problem with ionic serve, i’m getting Application not found error message. See the image below, hope someone can help me with this one.

Maybe you have a firewall blocking the ionic serve process from listening on

I’ve already tried to turn on and off the Windows Firewall of my computer, but it’s still not working.

Which browser are you using? Same problem I had faced with Chrome. I have installed Firefox and the issue is now resolved. :grinning:
