Customboard is not been detected by STMCube Programmer

[Ayu]

When I am connecting by STM32 custom board with Cube Programmer using STLink, its not been recognized by it. But the same board and ST-Link is detected by STM32 Cube IDE and stlink utility. So I want to know what the reason can be. 

Note development board is been recognised by cube programmer.

Is it a genuine ST-Link?
