Sometime i have a problem, connection is dissconected by error view^

[2025-10-07T17:15:46Z WARN  lan_mouse::emulation] releasing keys: 192.168.0.188:44609 not responding!

And i have work around for it (windows client)

Its powershell script, its rerun client by error in stdout

try {

        if ($Global:LMProcess -and $Global:LMProcess.HasExited) {
            Log "[!] lan-mouse crashed. Restarting..."
            Start-LanMouse
        }
    }
}
finally {
    # cleanup при выходе скрипта
    Log "🛑 Watchdog stopping. Killing lan-mouse..."
    if ($Global:LMProcess) {
        try { $Global:LMProcess.Kill() } catch {}
    }
}

Maybe add this feature to main project?

I would prefer to fix this within lan-mouse. Technically you should be able to reconnect automatically? Does that not work?

No, now it's not work. We don't have automatic rerun for it.

I have the issue as well and looking at the code, it seems that we disconnect (and controls are stuck on slave)

self.emulation_proxy.remove(addr);
self.event_tx.send(EmulationEvent::Disconnected { addr }).expect("channel closed");

Maybe some kind of retry before disconnecting?

@F1st3K does this start with elevated privilege to workaround #127 ?
