If the Android Backup Service is enabled on your device, some of your Chrome preferences will be saved and stored on Google servers visit the website. For Nexus and Android One devices, it is described under “Back up your data and settings with Android Backup Service” in this article. For other Android devices, you may be able to find help by looking up your device on this page. When setting up a new Android device, you may request that it copies the preferences from a previously set up device.
When a user asks Chrome to play encrypted HTML5 media (for example, watching a movie on Google Play Movies), Chrome will generate a request for a license to decrypt that media. This license request contains an automatically generated request ID, which is created by the Content Decryption Module, as well as proof that the CDM is legitimate.
Google can decrypt the device ID, but other entities cannot, and the encryption is designed so that two registration tokens for the same device ID cannot be correlated. On desktop versions of Chrome, the device ID is reset when the Chrome profile is removed, or when neither Chrome Sync nor any of the entities requires it for push messaging. On Android, the lifetime of the device ID is governed by the operating system and is independent of Chrome. Any messages routed to registration tokens containing a revoked device ID will not be delivered.
Websites you visit in Incognito mode are not allowed to send you push messages and therefore cannot get a registration token. You can manage and delete your saved credentials in the “Forms and passwords” section of Chrome’s settings. If you enable password management, the same kind of data about forms as described above is sent to Google to interpret password forms correctly.
The error message suggests the Windows Store is unable to connect to the server. But there are more possible reasons behind this error.
After generation, the license request is typically sent to a license server managed by either the content website or Google. Neither the license request, the proof, nor the request ID include any personally identifying information. After being sent, the license request is not stored locally on the user’s device.
If you do so, Android may restore backed up Chrome preferences when Chrome is first installed. This beacon’s URL is not sent to Google’s PWS unless the Physical Web feature is enabled. Users can also enable (or disable) the feature in the Privacy settings. The user receives a silent notification when Chrome finds a nearby URL. This identifier can be reset by reinstalling your operating system.
Additionally, a subset of low entropy variations are included in network requests sent to Google. The combined state of these variations is non-identifying, since it is based on a 13-bit low entropy value (see above). These are transmitted using the "X-Client-Data" HTTP header, which contains a list of active variations. On Android, this header may include a limited set of external server-side experiments, which may affect the Chrome installation. The registration tokens that are passed to entities contain an encrypted device ID, which is used for routing the messages.
This can make troubleshooting the error a bit complicated. However, if you initiate the Windows Update, these types of errors can occur for various reasons. Often times it will require a few computer restarts in order to fix it. Removing your security software can help at times though it’s not recommended.
