Hello @vyıbjf67 and welcome to the ST Community :smiling_face_with_smiling_eyes:.

Please check that the jumpers are correct on your board, especially the one for the ST-LINK.Then, try to connect your board with STM32CubeProgrammer. In the ST-LINK configuration area, try the following configuration:

• Serial number: Refresh to get your ST-LINK serial

• Mode: Under reset
• Reset mode: Core reset

Finally, try to connect your board.

Best Regards.

What should I do?

[STTwo-32]

ST-LINK Utility is obsolete. You have to use the STM32CubeProgrammer.

Best Regards.

Which board are you using? The DISCO or NUCLEO? Something else?

Make sure the pair of ST-LINK jumpers are in place.

Discovery and jumpers are in place.
