This error message means that the time of your server doesn’t match the time of our own server. In order to handle it, you can either check the time of your device and synchronize it or increase the value of the red window parameter which is set to 5000 by default. In case you do have this parameter in the request make sure it is big enough. You can increase it up to 60000 and send your request.
