Recently Roon stopped identify new albums for me. I bought some CDs by the Police and Eminem (so nothing too obscure) but Roon doesn’t identify anything for me anymore. I think it just doesn’t connect to the metadata server.
I’m running core on a QNAP NAS installed through the package by @crieke.
Can’t say for sure. Do you know, if your QNAP was able to access the Internet (in the time when RoonServer couldn’t)?
It seems as RoonServer had no connection to the Internet. There are a variety of possible triggers. It could have been caused by the QNAP, your router/network switches, RoonServer itself, or even by your internet service provider.
