Why doesn't my Lumia 930 accept any Qi charger anymore?

why doesn't my Lumia 930 accept any Qi charger anymore?

Could it be some hidden settning?

No there is no "hidden" setting. But inside the phone there are contact points from the back cover to the battery/motherboard and maybe that contact is bad. Try to push on the backside maybe that will help and check if the cover is well connected on the body of the phone.
Furthermore check if it also does not work on another qi charger to be sure it's not qi charger related.
The phone still should be under warranty so if above does not work sent it for repair/replacement.
