Are you able to view your playlists or perform any actions that require authentication (add comments or like/dislike videos)? If so, then it is not an authentication problem. I am unable to view my subscriptions and playlists when testing on the desktop, so it may be an issue with a missing library or similar. Try running cuteTube from the xterm: [CODE/]run-standalone.sh /opt/usr/bin/qmltube[/CODE] You can ignore any warnings about QNetworkConfigurationPrivatePointer. This is a known issue with QML.
