Which is exactly what happened - around 17:41 today (2026-05-22) I tried Restarting then rebooting Titan.
It would not boot at all and - despite again following these directions again - this is all I see:
So in Roon I try ‘Configure RoonOS devices’. I get this:
But single-clicking on ‘Done’ takes me back to that screen and into a loop 
.
Restarting my Mac Studio results in a Roon which cannot connect to Titan. Once again, I am forced to physically disconnect Titan’s power cord (the button on the front doesn’t fix this) in order to be able to use Roon at all
Very reluctantly I did so - as what seems like the only way I can ‘reset?’ Titan; and Roon can again see Titan!
The backup can not proceed; both IP addresses are visible again; no Jellyfish for either. The backup completed successfully without errors just before 18:00 PDT on 2026-05-22
Logs around 17:52 PDT
I hope you have enough information (from the logs, again - around 17:45 PDT) to help me fix this once and for all, please!
