Hello @wibergip,
I understand how frustrating it is when a system you rely on suddenly stops communicating after an update. Thank you for reaching out so we can get this sorted out for you!
While it might seem like a bug with your recently updated iMac app, the disconnect is actually happening on the QNAP side.
What happened: Recent updates to the Roon architecture introduced new underlying system and software library requirements. Unfortunately, the native QNAP operating system environment can no longer support these modern software libraries directly. As a result, the traditional QNAP Roon app (the QPKG version you have been using) fails to launch in the background. Because the server is effectively offline, your iMac Remote is stuck endlessly searching for it.
The Solution: To get your system communicating again, you will need to transition your Roon Server to run via QNAP’s Container Station (which uses Docker). Running Roon inside a container safely isolates it from the QNAP OS limitations and provides it with the exact modern environment it needs to run flawlessly. This will also prevent future QNAP updates from breaking your Roon Server!
Next Steps: You will need to install Container Station from the QNAP App Center and set up the official Roon image. We have a comprehensive, step-by-step guide to walk you through this exact process here:
Once you have the container spun up, your iMac will find the server on your network, and you will be back in business. Please review the guide, and let us know if you hit any roadblocks during the setup process—we are here to help!
