Logs show your RoonServer machine losing connection to the RAATServer instance on the Mac remote. There are two possibilities, based on what we can see in diagnostics:
There appears to be a separate subnet on this LAN. If Roon Remote is switching between subnets or network connections, it will lose sight of RoonServer.
The second possibility is that third-party software or a stateful firewall is interfering with RAATServer on the Mac or RoonServer. In most cases, this will be antivirus software.
Chiming in here with the same problem. Roon remote on PC is constantly losing connection to Roon server on Mac. Also have a Tailscale subnet on PC that when disabled Roon Remote works. This is a new problem for me though, in the past Roon Remote on PC worked fine even when using Tailscale & other VPNs.
@404 for myself it doesn’t happen as much, just on occasion. After one restart it’s stable, until next time. But now that i think about it, it started happening after i installed Tailscale…
Which version of Tailscale are you on?
I’m on 1.70.0
Unfortunately, the use of a VPN falls outside the scope of support. I’d post over in Tinkering to see if anyone from the community may help you with getting things functioning.
Roon will automatically try all activate network adaptors. You can disable any network adaptors you don’t want Roon to use if that is an issue for you.
