Error in initializing ST-LINK device. Reason: No device found on target.

Hello.

I'm having problems to program an STM32G474-NUCLEO Board with an external STLINK programmer. I'm using the STDC14 on-board connector and following the instructions given in the the board user manual. However, I get the error: 

"Error in initializing ST-LINK device. Reason: No device found on target."

The manual does not gives any other explanations about the use of external programmers. I suspect it could have something to do with the voltage supply. 

I would appreciate any recommendations or hints about the issue.

Regards.
