No, I have not seen or heard of that. Essentially this started on its own - and when I opened a device which hadn’t used Roon for a while, all the album art showed up, then deleted itself. I’ve even tried re-installing the entire library.
The NUC is a dedicated Intel, Linux / ROCK. Not being a techie I’m not sure what else to add on the network. There is a Pakedge switch connecting incoming internet to the NUC and to many devices via ethernet. But the problem is with wifi-connected iPads (x3), iPhones, and Macs. Storage is a QNAP NAS - but I have zero artwork for anything either stored or from Tidal, so not sure if that’s an issue either.
It all disappeared about 3-4 months ago and while you occasionally get one image popping up it’s all blank.
So the only thing that worked was rebuilding the database. Lost all customized content but ok. (Tried all the above with no luck.)
Then: 2.0 came out, updated itself on all devices, but like everyone else, my intel NUC is “not compatible”. Unlike fixes on screen: it does have access to the internet. So now no music at all. Beyond frustrating since there’s no obvious answer a non-techie could ever work out.
I enabled diagnostics and I’m seeing authentication errors when Roon tries to access your storage. Please do check your storage and backup locations and verify the authentication is working right.
Unfortunately, what happened to you was an issue we identified this weekend where Roon Nucleus is erroneously updated to a lower version. Here is the message we sent to those reporting this issue and attached below is the knowledge base article needed to resolve this.
We’ve identified an issue with our update server erroneously serving 1.8 Legacy builds when it was not supposed to, and have since corrected this behavior.
For those who have already been downgraded to Legacy 1.8 and wish to re-install Roon 2.0 on their Cores, please follow the 2.0 migration guide on our knowledge base, linked below.
1.8 Legacy is compatible with 2.0, so your Roon database should remain intact. If you encounter any further issues after following the guide, please start a new support topic and let us know, thank you!
Go to the /Data/ share (instructions) and create a folder called branches
Download the following file: roon_2-0 (It should be named roon_2-0 and saved with no file extension)
Copy the file into the branches folder previously created
Rename the file to roon (instructions on how to rename files: Windows / MacOS)
