For your connections/monitors to work correctly you need to setup the ITmanager.net Private Network Connector (PNC). The connector acts as a VPN giving you secure access back to your IT network.

If you have setup the ITmanager.net Private Network Connector but you are still not able to connect. When configuring your connections/monitors be sure select the last field called "Connect to Private Network" and from the drop down chose the "connector" you setup.
