Depth attachment empty

Hello! I am trying to learn vulkan and my work is going pretty well, except for a depth buffer, i can not make depth buffer work. This is what i see inside actual application, also i checked render doc and depth buffer attachment is completely empty(white)

This is rendered with VK_COMPARE_OP_LESS_OR_EQUAL, if u use OP_LESS, i get no image at all, i assume this is because everything got discarded due to empty depth buffer attachment

What are most common mistakes in terms of depth buffer? I understand that this is a hard task to help me without providing whole code, but it is quite a lot of code. I am using default options for creating depth buffers and pipelines which are provided in many tutorials.
