Describe the issue

My Roon setup was working flawlessly for more than two years but suddenly the Linn DSM/3 disappeared and even AirPlay2 is not possible any more.
My setup: Roon server 2.0 (build 1490) running on Mac Mini (2023 M2, Sequoia 15.2), software serial F2A74E50-56BC-4D67-BF07-342917F6095B, Linn DSM/3 (firmware 4.108.550 - setting for Roon Protocol is “Roon Ready”).
I have logged out and on, restarted all systems including router several times without any success. On my Linn account my DSM/3 is shown as “online” and I can change all settings so the Linn is definitely connected, I can stream music via Tidal and Qobuz apps via AirPlay2 but my Roon app is not even showing my Linn via AirPlay.

Any help would be highly appreciated - THANKS !!!

Describe your network setup

Roon server connected to FritzBox router via LAN CAT8 cable, LINN DSM/3 connected via Mesh to router

Hi @Stefan_Gutheil,
Thanks for reaching out to us to ask about this issue. To help narrow down the source of the problem can you please test whether the problem persists if you connect the Linn directly to your router? Have you had problems with any of the other devices on the mesh access point?

Hi Daniel,
Thanks a lot for taking care of my issue! I tried your hint below and connected my Linn directly to the router via CAT8 cable, nothing changed, so obviously no network issue.
What I did in the meantime is a rollback of my latest OS update on my Mac Mini (with the help of a local IT expert) and … the Linn was back again! So it seems the latest update to Sequoia 15.2 has changed something in the settings. Not sure yet what caused the issue but I’ll find out and let you guys know. Pretty sure I am not the only one with this problem.
For now, problem solved - and thanks for your support!
Stefan
