Hi @darkless,
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
To confirm, you have tried the following:
- Reboot of Roon Core
- Reboot of networking gear
- Deleted the files named “Devicedb-prod.zip” and “Devicedb-prod.zip.etag”
Is this issue occurring on all remote devices?
