Serviio not available after system wake up event

Hi,
I have an issue that shortly after Serviio checks for a new version, I get a "System wake up detected" event which then restarts UPnP services

This causes my Samsung TV (or other DLNA clients) to loose connection with the Serviio server.
This loss of connection is then restored after some minutes (perhaps 10 or so???)
Or if I start/stop the Serviio Window services (via net start/stop serviio)

My Serviio computer does not have access to the internet - so the check fails - I wonder if this causes the wakeup event.
If so, can I prevent this check.
If not - what else could be causing the wakeup event and the service not being seen?

Thanks
Carl
