When I open the app, I'm told "Waiting for Roon Server." Roon has access through my firewall and everything is on one computer. I have this problem all the time. I have been able to fix it by changing some of the setting to "Old" and reloading the app, but that doesn't always work. This seems to only be a temporary solution since this happens so often. I am running a Mac and connecting to KEF wireless speakers. No nucleus.
Describe your network setup
Quantum fiber wifi. Everything connected by cables directly to my Mac.
The MacOS 15.x Sequoia Privacy & Security settings will intermittently restrict RoonServer and RAATServer’s local network access, disrupting both remote (control) and endpoint connectivity.
If you haven’t already enabled Local network access in System Settings → Privacy & Security → Local Network, please take that step for due diligence.
Please let us know if you’ve already tried this step.
