Error in final launch sequence:

Failed to execute MI command:

target remote localhost:61234

Error message from debugger back end:

The usual suspects:

• Check VCC voltage. Note that programmers typically do not supply power.
• Check part orientation. Pin 1 is on the lower left when "STM32" reads from left to right.
• Can you connect in STM32CubeProgrammer? Does it display a voltage?
• Do you have an official ST programmer or a counterfeit one? STM32CubeIDE does not play well with knock-off programmers.
