OPNsense 25.7.4-amd64
Tailscale plugin 1.2 (1.88.1)
I have multiple firewalls running Tailscale. On November 1 two of these dropped off the tailnet. The hosts are still online, but when I look at their Tailscale status it shows that the service is running, but no peers are visible. I restarted the service but it's still not connecting to the tailnet. Key expiry is disabled for these hosts and they were initially connected using a pre-authentication key.
I don't see any Tailscale logs. What's the best way to troubleshoot this before I just update the firmware and reboot without knowing?
