**Config**
        {
"cleanCache": true,
                "platform": "HarmonyHubWebSocket",
                "name": "TV",
                "hubIP": "192.168.87.20",
                "mainActivity": "Watch Apple TV"
        },

**Additional context**
Problem happen before I added the clean cache line. I think it worked before I changed the name of the "name" parameter. I can't remember the old name. :-(
