Error unable to locate device

[stmproblem348]

Hello everyone, 

I own a STM32 NUCLEO G071RB. The STM CubeIDE software was working fine for a couple of weeks until I got the error message:

Target no device found

Error in initializing ST-LINK device.

Reason: No device found on target.

The board still lights up and now when connected my computer open the node G071RB file (see image attached).

I have tried all solutions from reinstalling STM32 CubeIDE to installing STM 32 programmer. But nothing is working. I have attached a file below that can help understand the problem.

Thank you for your time and consideration.

Hello @stmproblem348 and welcome to the Community :) 

Check that the jumpers are correctly configured on your board.

Make sure that your ST-Link firmware is upgraded.

Try to "Connect under reset" or "power down" mode.

Thanks, one of my ST link jumper's cap went missing.
