Try to set offline mode

  1. Click File => Settings (on a Mac, Android Studio => Preferences) to open the Settings dialog.

  2. In the left pane, expand Build, Execution, Deployment and then click Gradle.

  3. Under Global Gradle settings, check the Offline work checkbox.

  • Your proxy needs authentication and the authentication you supply is invalid or your proxy does not allow to request that URL with the authentication details you supply. – Gautam Surani Jun 20 '18 at 12:23
