I have tried this commands:

npm rm -rf node_modules
npm install

ionic cordova platform remove android
ionic cordova platform add android

npm install -g @ionic/app-scripts@latest
npm install -g @ionic/app-scripts@latest --save-dev

cordova clean

again installed ionic@latest

try to create a new blank project but didn’t get any help…

Why the connectivity problem continues am I missing something?

Same issue, after updating to latest version

Also reproduced this after updating from v.4.0.2 to v.4.0.3. My app-scripts version is a bit older than the one reported. Problem thus seems to be in ionic 4.0.3, not in ionic-app-scripts?
