I followed the suggestion to use a VPN and have an update to share.
Environment:
- Roon Core on a server in Japan (ISP: OPTAGE, Osaka)
- Qobuz Japan subscription
What I tried:
Connected to ProtonVPN (Japan server) as suggested by support.
Results:
With VPN connected:
- Previously unavailable Qobuz albums became searchable and playable in the Roon client

- Non-library Qobuz albums were also searchable and playable in the Roon client

- Roon ARC: library albums play fine

- Roon ARC: searching for non-library Qobuz content returns “couldn’t find this album”

After disconnecting the VPN:
- The improvement in the Roon client persisted — albums that were previously unavailable remain playable

- Roon ARC behavior was identical to the VPN-connected state (no change)

The main issue I was experiencing has been resolved, so I’ll monitor the situation for now. Thank you for the
suggestion.
