Waiting for Ionic connectivity with ionic-app-scripts issue
The reason is in that the app starts with 0.0.0.0 IP address. Try to add in our command "--address localhost" part. So
ionic serve --address localhost
Try the modified part. And try executing "npm start" command
{
"name": "name",
"version": "0.0.1",
"author": "Ionic Framework",
"homepage": "http://ionicframework.com/",
"private": true,
"scripts": {
"clean": "ionic-app-scripts clean",
"build": "ionic-app-scripts build --aot --minifyjs --minifycss --release",
"lint": "ionic-app-scripts lint",
"ionic:build": "ionic-app-scripts build",
"start": "ionic-app-scripts serve" //instead of ionic:serve, write start
},
If none of these works, then make sure your FIREWALL is OFF. (into antivirus software as well.)
