More hints …
I had the UI app open on my Windows 10 PC , nothing playing
As the scheduled time passed , the appropriate messages started Snapshotting etc
Then the connection stopped , I closed the UI app, after an hour I restarted the UI app to find the BU had succeeded and the connection was remade without me restarting the server.
Do you want the logs ?
I see this in the UI PC LOgs
