Client Validation Failed / Drivers Hub Not Found

As we introduced a client validation mechanism in v3.4.0/1, the client must prove its identity to the server to ensure it's official. The algorithm involves using the current time, which allows a maximum deviation of 5 minutes (ahead or behind). Thus, you have to ensure that your device's system time is accurate. Otherwise, the validation may fail.

Also, please make sure you have cleared the cache of the browser to ensure that you are using the latest client. Old client may not be able to pass the validation.
