· No, Roon Server is not running.
· I can't turn on Roon Server, I need help.
Rock is in my network and is running. Server software is not running and NUC says restarting is not possible, please contact support.
NUK as core with rock. Qnap Nas as store for music. Mac Studio 2025 and iPad Air 2025 as control. Router AVM 7690
Please wait until cloudflare gets its current issue resolved, then try again.
Good day @MacTan !
What @BlackJack saying is correct.
By now the CloudFlare is claiming to be restored.
Please try again and let us know please whether it is working.
Thanks!
Regards.
Hi alex_h,
You are right. By now my system is running. iPad works very well. The Mac Studio with OS Tahoe 26.1 has still problems to connect to rock. In system/privacy I very often have to turn Roon off and on. When I start my Mac again then, mostly it will run. When this will not help I have to take the router from electricity and DSL connection and start the whole system new. But this is stressful. Especially the search after the problem.
Hope you will find the problem.

Hi @MacTan,
Can you confirm your ROCK and Mac are on the same local subnet? If you could, please reproduce the issue, grab the specific date and time, and share that info here.
From there, we’ll take a closer look into your Roon Server diagnostics. Thank you! 
Hi benjamin,
yes I can confirm, ROCK and Mac are on the same subnet. I have only one home network with one router and all my devices are in the same subnet.
Just now I cannot connect with the Mac to the Roon software. With the iPad it functions.
I will come back to you as soon I found the fault.

MacTan
Hi benjamin,
now I can report to you that I opened system settings/data protection & security/hard drives full access. There I disabled the Roon app and enabled it again. After this I shut down my Mac and restarted the Mac. After these steps my Mac has access with Roon again. The Mac uses OS Tahoe 26.1 as operating system.
Does this help you?
If you need any further information please let me know.

MacTan
And by the way, can you please delete “Peter” from my name which is displayed. In the past this was done already but since some time it is displayed again. Thanks in advance.
Hey @MacTan,
Apologies for the confusion here, but are you still having issues? Recent macOS updates have tighter (and more obfuscated) security settings than preceding MacOS versions, and may cause some users to need to manually re-enable such settings.
Our development team is aware of this and is investigating a long-term solution. Until then, after a reboot, a manual re-enabling of such settings may be required.
Thank you! 
Hi benjamin,
yesterday morning, after disabling and enabling the Roon app the Roon software was running. This morning it is good as well without disable and enable.
But since OS Sequoia and as well with I OS Tahoe I had to do this job several times. Nearly every second or third day. I can see no improvement since Tahoe up to now. Frustrating.
Regards
MacTan
… and many thanks for the removal of “Peter”
Hi benjamin,
today Sunday 23rd November local time 10:20 a.m. I had to do this workaround twice. Including the search of Roon for the Core with my IP address. The first workaround brought no result. Roon did not found the core. Not until the second shut down and restart of the Mac.

MacTan
HI @MacTan,
Thanks for the update, and I’m sorry you’re needing to re-enable such settings. This is unfortunately a known issue caused by the recent macOS updates - our team is still working on a fix, but we’re also keeping our fingers crossed Apple releases a fix as well.
Until then, you may need to continue doing the same process each time after your Mac is shut down / booted up.
