Scan Schema and Show Schema not showing information

[SciGno]

The context menu for Scan Schema and Show Schema does not do anything. Even the side bar 'Cassandra Schema' is not displaying any information. What am I missing?

I have the following for my settings:

{
    "cql.address": "192.168.1.161",
    "cql.scanOnStartup": true,
    "cql.schema": {
        "contactPoints": [
            "192.168.1.161"
        ],
        "hosts": [
            "192.168.1.161"
        ]
    }
}
