You are using Unified Agent with IPSec VPN connection. They are competing for connectivity and sometimes resulting in service interruption.
Unified Agent and your VPN are competing for connection; causing conflict or tunnel flapping.
Adding the VPN IP into the Portal:
Select Service> Network> Bypassed Sites> Bypassed Domains

You do not want to send your VPN connection through our service because we cannot see that encrypted tunnel.
