I tried to re-upload the Firmware on the NUCLEO-F411RE with ST-LINK Utility. But i get this error.

13:56:05 : ST-LINK Firmware version : V2J27S15
13:56:05 : Connected via SWD.
13:56:05 : Connetion mode : Normal.
13:56:06 : Unknown device ID!

I also tried the connect under reset but it also did not work. Can anyone help me?

I would be glad to get an answer.
