st link server is required to launch the debug session

Hello,

using: STM32CubeIDE 1.10.1 on Windows 10

I have not used the debugger for a week or so, I didn't do any updates (okay, Win 10 probably has, managed by company...), but all of a sudden when I want to start a debug session, this message pops up:

st link server is required to launch the debug session

Why's that?

Edit: I am an absolute beginner when it comes to STM debugging tools.

Because I always worked on many different platforms, I mostly rely on LEDs and UARTs for debugging...

Hello @Community member​,

Please make sure to close all instances of STM32CubeIDE, STM32CubeProgrammer.

If it doesn't work, you better update the firmware version check debugger settings. For example:

Thanks, now after a re-installing of the ST-LINK server software and a computer restart, it's working again.

Although Win 10 didn't like the install file, came with a warning.
