Could not resolve com.android.tools.build:gradle:2.2.3

Question

I\'m working on a mobile app project for work, but often when I attempt to run the application it gives me the following error:

Error:A problem occur

Answer 1

I've had the same pb, managed to resolve it adding in gradle.properties

systemProp.https.proxyHost=
systemProp.https.proxyPort=

I was missing HTTPS property, there was only HTTP setted so it was working sometimes, and not for the https links gradle used.
