CubeIDE 1.19.0: Failed to enable Live Expression. Connection failed

Gaston · ‎2025-11-12

This does not happen in CubeIDE 1.15.1 and the solution suggested in this post does not work either.

How can I fix this issue?

Thanks in advance,
Gaston

It says, "Connection failed" - can you do anything else in the debugger?

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.
