Problems with SSL tunnel that you got a message: "failed to connect to hub"
If you have a data center (Hub) connected to another data center (Hub) and configured the UIM tunnel to go over an IPSec tunnel on the router
The UIM tunnel and IPsec tunnel will interfere with each other
Any environment that is using Tunnel inside a VPN connection between hubs.
It just needs to be a straight connection over the internet, using ports 48002 not the tunnel/client Server (Port 48003)
