Failed to execute MI command

I recently started getting the following error when trying to program my nucleo-32 L432KC board:

 

 

 

Error in final launch sequence:

Failed to execute MI command:
target remote localhost:61234

Error message from debugger back end:
localhost:61234: Connection timed out.
Failed to execute MI command:

Error message from debugger back end:

localhost:61234: Connection timed out.

 

 

 

I have tried using the cube programmer to erase the flash memory, but when trying to connect with "Mode: Normal", I get an error: "Error: ST-LINK error (DEV_TARGET_HELD_UNDER_RESET)". When changing the Mode to "Hot plug", I am able to connect to my MCU, but the "Full chip erase" operation gives me the error: "Error: Mass erase operation failed.Please verify flash protection".

Does someone have an idea what could cause this? Programming the MCU worked just fine a day ago.

Ok this was solved by breaking the S9 solder bridge.
