Ionic/Cordova: "ERR_CONNECTION_REFUSED"

Question

After messing up with some plugins trying to make WKWebView working without success, my app on every device but the browser throws this error

Application Error net::ERR_CONNECTION_REFUSED (http://localhost:0/)

• I removed cordova-plugin-webserver
• ionic run doesn't work, ionic run -l works

Anyone has any clue on what's going on?

These are my plugins

com.telerik.plugins.nativepagetransitions 0.6.5 "Native Page Transitions"
cordova-plugin-console 1.0.3 "Console"
cordova-plugin-crosswalk-webview 1.8.0 "Crosswalk WebView Engine"

cordova-plugin-facebook4 1.7.1 "Facebook Connect"
cordova-plugin-inappbrowser 1.4.0 "InAppBrowser"
cordova-plugin-keyboard 1.1.4 "Keyboard"

cordova-plugin-whitelist 1.2.2 "Whitelist"
ionic-plugin-keyboard 2.2.1 "Keyboard"
twitter-connect-plugin 0.5.0 "Twitter Connect"

I have these in my config.xml

<access origin="*"/>
