Roon CANNOT FIND any of my devices

I also see that 6 hours ago it seemed to have been running, although with Tidal issues:

Was this before or after you did the update, and has it become worse since?

In addition, I see that you had a frequent “stops after a few hours” issue already in the past, but it was never resolved because you didn’t answered the questions asked by support. This means that there was always some problem in your setup. The new one may or may not be related, but we may well have to drill down to basics, so it may need some time and definitely your collaboration.
