Hi @philip.cancel,
I’ve moved your second issue with Roon into a dedicated troubleshooting thread since it will require separate troubleshooting steps from ARC.
Are you able to describe how this network topology is connected? If your RoonServer is on a laptop relying on WiFi, then your up- and downstream connections are both vulnerable to interference in the signal. Roon might struggle on occasion to reach the internet and devices.
This will also occur when the laptop is closed and hibernates - RoonServer, even if it open in the backgrouhd, loses network permissions.
You can partially mitigate these frustrations by verifying that your laptop has good line-of-sight to the main, upstream router rather than a mesh node or wireless access point. If you have control of your router settings page, you can verify that multicast and IGMP snooping are enabled.
