all products have been deleted from my shop

[Einzelhandeln]

Hello,

all products have been deleted from my shop. What could happen, does anyone know? Problems with the supplier are ruled out as other products are also gone. At short notice I gave a third party provider a code for access to the app with restrictions and after 2 hours all the products are gone. Again the products from my supplier can no longer be imported automatically. something is wrong with my shop.
