@Singleton thx for the advice unfortunately I did all of those and is still an issue. It has been happening since the last Roon server software update.
Let’s make another attempt on your Mac mini if you will Shaun…
Flush The Cache
Step 1. Perform a backup and shutdown all endpoints and your server.
Step 2. Delete Roon
Step 3. Reboot
Step 4. Open the “Go menu” located in your Apple menu (Finder) select the drop-down “Go to folder” and then enter each line below in turn in the field to reach a given directory. Once there delete each parent directory that references the name “Roon”.
Example: When performing this action on my Macbook using “~/Library/Saved Application State” it reveals the hidden directory “com.roon.Roon.savedState”. In my example, you would select this directory for deletion.
~/Library/Application Support
~/Library/Saved Application State
/Library/Caches
~/Library/Caches
Step 5. Reinstall Roon
When reinstalling you should see a prompt requesting that you Allow “Roon” to find devices on local networks. Select “Allow”
Step 6. Power on your server and endpoints. Reinstall your backup
