Synology DS cloud broken

The latest version of Synology’s Android app DS cloud stopped working with the Cloud Station package on my DS508, which is stuck with DSM 4.0. The app was released on Google Play March 2nd 2016 – version 2.6. Cloud Station package version is 2.2-3047.

CloudStation is running on the DS. My Android phones and tablet are shown as offline in the client list. On the devices DS cloud is shown as running, but no files are synchronized. Synchronization is missing both ways – files are not pushed to the phone, and files updated on the phone are not pushed to the DS.

To fix this I went to and downloaded version 2.5 of the app. Before installing, the existing app has to be uninstalled, so reconfiguration is needed.

I created a support ticket at, so they are informed.

Update, March 10th 2016: Synology reported back to me that they had analyzed my logs and found the problem: The database was corrupted. So it must be a bug in the database upgrade in version 2.6 of the app. After clearing the app data and reconfiguring it works perfectly.
