Description of Issue

Just updated my network equipment to what is listed above. When checking network traffic, my installer noticed the following:
There are a bunch of blocked connections from the Nucleus, it’s trying to talk to “xx.xx.xx.xxx”, which is an IP address in the infrastructure zone, so it’s being blocked. More interesting is that IP address isn’t currently in use, nor was it used by the previous network hardware, so no idea who it thinks it’s trying to communicate with?
When I first installed my Nucleus I was not aware that Roon could not cross vlans, so it is possible that the initial setup included a backup or other device in another vlan. But I have no idea why the Nucleus would still be attempting to connect to an unknown device in my infrastructure vlan.
Any advice on how to troubleshoot?

Hi @Kurvenal,

Fully reset the database and see this changes the behavior:

  • Create a Backup of your current Roon Database
  • Stop RoonServer from running in Nucleus’s WebUI
  • Navigate to your Nucleus’ Database Location
  • Find the folder that says “RoonServer”
  • Rename the “RoonServer” folder to “RoonServer_old” and “RAATServer” folder to “RAATServer_old”
  • Reinstall RoonOS from the WebUI**
  • Restart the RoonServer in the WebUI to generate a new Database
  • On the Roon controllers, press “Use another Roon Server” and connect to the new database
  • Restore the Backup
