create-react-app - Why localhost is not working?

After creating a new react app using create-react-app, once I start the dev server via npm start, the server started and shows this:

I'm sure that until last week I could open http://localhost:3000 to see the new created app in browser, but now it doesn't work any more and shows this:

But, it works if I open http://192.168.119:3000

I haven't changed anything inside my .hosts file.

Does any one know why I cannot use http://localhost:3000 any more?

I had a similar problem, and checked that my VPN ( I use warp) is turned off already. However, when I turned it on, my local worked again.

Little late to this, but i came across the same issue; Turned out my vpn app was running preventing me from accessing the app on http://localhost:3000. So, turning off the vpn should resolve the issue

Thanks for your help guys. After emptying the browser cache and flushing the DNS it's now working again.

Have you used an agent?

ping localhost, check it is 127.0.0.1?
