Roon 1.8 (783) on QNAP TVS-871 with 16GB and i3 CPU.
All networked in over cable to my Draytek router.
Roon bridge on DietPi with USD NAD DAC attached into a Meridian pre-pro. 1.7 build (571).
In my GUI for Roon, I see a spinning circle icon in the top right hand corner, next to the bookmark icon. If I click it, it says “Metadata Improver: Paused”. Also, says “Roon is having trouble verifying your connection with our servers, so metadata improvement has been paused. Check your internet connection and make sure that you’re running the latest version of Roon.”
Internet radio works fine and I can also play music from Qobuz through Roon, so this would suggest internet access from my Core is ok?
