Managed wallpaper setting is failing in iOS 11.0.2

Managed wallpaper setting is failing in iOS 11.0.2 devices as server session invalidated. But the wallpaper is applied to the device. Didn't find any clue on it. Since the image is sent as encoded image there is no need for the device to configure the server / it is representing anyting. But these failure hapens someimes and sometimes not.

Could anyone found the following behaviour?
