· Do you have a mesh network? (Google Mesh, Eeros, Ubiquiti, etc.)
ARC Status
· ARC is *Not Ready*
Roon Error Code
· The ARC settings page says "Not Ready," but I can still connect to ARC via cellular data. I'm having another problem.
Describe the issue
After playing flawlessly all week, I get "NOT CONNECTING TO SERVER" error messages. This happens 2-3 times a week. Previous support request for this was closed.
Intermittent ARC connection failures like this usually come down to the server losing its external reachability for a moment, so I’d like to narrow down where that break is happening.
To get a clearer picture, a few things would help:
What does the [url=https://help.roonlabs.com/portal/en/kb/articles/networking-best-practices]Networking Best Practices[/url] guidance suggest about your setup, especially whether Roon Server is wired directly to the router and whether there are any mesh nodes, switches, or double-NAT devices in the path?
When ARC shows “Not Connecting to Server,” does the diagnostics screen in Settings > Roon ARC show any specific error at that moment?
Is this happening on mobile data, on WiFi away from home, or both?
If you can also tell us your router model and whether the issue tends to happen at roughly the same time of day, that may help us spot a pattern. If you have a recent timestamp for one of the failures, share that as well and we can review the server side activity around it.
We can take it from there once we have those details.
