Hi Arjan,
Is this repeatable ?
Simplest way to "repeat" it would be to Rightclick on the Item (Album) in the Library Area and choose Streams + Get Coverart from Tidal.
I tried to Google it, but it doesn't bring me much, probably because the message is in Dutch. But if I had to guess I'd say something with a Proxy (or (DNS) Naming service somewhere.
It would be helpful if you can switch your OS to English, so I can see the message in English. Of course I tried a few translations but I'm confident the English message is quite different. This already starts with the "opgehaald". But there has to be more (changes) because I find nothing in (my) English.
Anyway I have never seen such a message.
Regards,
Peter
PS: A few days ago I had a similar issue, for the very first time. That implied an error on the Tidal side, but I could not do much with it. That did not obtain the tracks themselves, while playing it through the Tidal player itself worked. I am mentioning this because I recall the same "resources.wimpmusic.com". And that *is* from the images (Coverart).
Which album is this happening to ? hey, trying it myself could be way more easy than you switching the OS to English.
