I have installed Mbed Studio 1.4.5 and tried building blinky example for STM32H747i-disco board and was able to successfully build and run the application on the target board. I can see the LED blinking. But when I start the debug session, I get this notification.
localhost:50001: No connection could be made because the target machine actively refused it.
Here is the log at the output. Any idea what could be wrong?
