100 Lite Nodes can be run on 1 server or 1 VPS(Vultr) server. This means that if you have up to 100 Lite Nodes, you will see 1 server online in the Nodes tab.
Example 1: If you own 100 Lite Nodes, you will need 1 server. In your dashboard you will then see 1 Server online.
Example 2: If you own 3 Smart Nodes and 10 Lite Nodes, you will need 4 servers and you will see 4 servers online.
To ensure all your nodes are running correctly check to see if your licenses match the amount online.
