service can't be exited using CTRL+C inside terminal

Sometimes on rare occasions it can happen that one can't exit the service using CTRL+C because it hangs on something. It will close all sessions and such but pressing CTRL+C another time just prints:

^C2021-06-30 16:04:44,863 INFO: Service was terminated.
2021-06-30 16:04:44,863 INFO: Shut down session service.
2021-06-30 16:04:44,863 INFO: Stop all sessions.
