I am having troubles like this quite frequently as well. Up to now I though that Qobuz doesn’t offer the specific album for streaming and I didn’t really investigate.
Right now it happened again with the album “Alright Jack” from a band called “Home Service”. Please perfectly via the Qobuz Webplayer but Roon tells me
Same is happening with John Denver’s “Earth Songs”, but I saw that Qobuz seems to have removed this album from their catalogue
I’ll report additional albums with identical behaviour.
I just checked on this again and both of these albums are currently playing okay for me from Qobuz — Are you still seeing the error from Qobuz for those two albums? Are you using a US Qobuz account?
The John Denver Album which I had marked a favourite doesn’t work but as I already wrote it seems that Qobuz removed this album from their catalog. I deleted the album. I searched again for the album on Qobuz and saw that it’s still there, but it seems to be a different version of the album. I added this version which works without problems.
The “…Rare Tracks…” album works as well.
So no more troubles on my end. Thanks for getting back.
