Hi @Peter_Zwiefelhofer — Thank you for the report and sharing this observation you have made with us. The insight is appreciated!
I agree with John’s post above, if you could please provide a brief but accurate description of your current setup using this link as a guide it will give us a better sense as to what gear you are currently working with 
Additionally, have you verified that there are now firewalls or antivirus applications potentially blocking the communication between the mentioned Win10 PC and ROCK?
