I use Norton360 with Lifelock for internet protection. Included in my service is Norton VPN. Recently Dorico 6 pro stopped loading, which the error indication mentions nm socket not loading. The correction involves excluding Dorico 6, Groove Agent, Halion sonic, VST 2.x and VST 3. Go to Norton VPN, settings, split tunneling, exclude apps, edit apps. You have to list all 5 .exe files. With this configuration, Dorico loads, keeps all your audio and input devices connected every time you start the program.
