I'm having the same problem with the (ST-LINK GDB server) connection, when I switch to 'ST-LINK (OpenOCD)' I can debug the application.

When I use the (ST-LINK GDB server) I get the following message:

In my case, I get it to run by setting --> menu Run.Debug Configurations. Debugger:

1) connect to remote GDB Server Port Number change to not 61234 --> 61238, (while still chose Autostart local GDB server, Connect to remote GDB Server is not chosen, just change the number

2) Reset Behaviour: choose Hadware reset

Then it runs smoothly every time.. 🙂 :), I really don't know what is the best/correct answer, just sharing my experience...
