I tried the following
1．Settings → Setup → Restart Roon with Clear Image Cache
2．Unplug the hub, rock, router, PC power and restart
3．・ Database reset + log out with ROCK
・ Log in with another PC and check the display.
・ Log out to another PC
・ Log in again with ROCK and reset
４．Log out of TIDAL and log back in from the Roon Settings-> Services tab
５．Disable firewall on all involved machines

Thanks for sending your friend’s ID, I was able to take a look over their logs.
This is strange, it looks like they are able to play TIDAL content ok, but when it comes to downloading the images, they are getting networking errors. There also appear to be some other network errors when trying to contact our discovery service.
I noticed that your friend is making heavy use of IPv6 communication and I’m wondering if this is playing a part in the issue. Is there any way that they can try to disable IPv6 and see if this helps? What does the network setup look like, are they using any firewall device such as PiHole?
