So your debug probe is found, but the target is not. Check the wiring and correct power supply of the target. Try a known-good target like a nucleo board for cross-checking.

Is your code putting the CPU to sleep, and/or disabling the debug pins?

First try with the ST-Link Utility - to take Keil & AC6 out of the equation.

If that works - then the problem is with your Keil & AC6 setups;
If that doesn't work - then you have a fundamental problem.

When the ST-Link Utility can't connect, it gives suggestions to resolve the situation - follow them.

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
