Malicious connection from Insteon Hub to 20.185.183[.]67

My router has been blocking these connections.

Sent from your Synology Router- SynologyRouter.

The IP seems to be from Microsoft. What is Insteon doing with Microsoft?

The Insteon app uses Azure to handle push notifications to mobile devices. If a device was activated and you have notifications set to On it could just be that call, but it would originate from your phone not the Hub.

The Insteon Hub uses Azure for time sync. If your IP notation means "on port 67", and no device was activated, it would be the Hub making sure it has the right time for your location from the NTP servers.

Thanks. That explains it.
