Hey @David_Waring,
Thanks for reaching back out, and my apologies for any confusion here! As @Carl mentioned, the system will auto-close threads once a solution has been found. I’m sorry to hear you’ve run into this issue again!
Unfortunately, we don’t have specific identification on the issue you’re having (perhaps you were thinking of a similar issue where many users had their cores stuck on initializing?)
A few things to note, if possible, please update all your Roon devices to the most recent build (988) and see if that helps.
We’ll need to enable diagnostics on your account and grab a set of logs from your Mac Mini to better identify what might be going on.
Please use the directions found here and send over a set of logs to our File Uploader? Please include a timestamp of when you are attempting to establish connection, or when you lose connection to your core. This will help the team pinpoint things more specifically.
