Collect ntopng Data for Grafana and show Hosts on a Map not working

[EddyT]

Hello,

I have pfSense running quite good and all is working kinda okay.
I got one problem. I am collecting Data and transferring it over InfluxDB to a Machine
running Grafana. As for now it all works but not the Map.
It looks like this:

Why isn´t it creating any Information on the Map? What do I have to check? I dont really understand Grafana so good maybe one of you can help me here.
Please tell me what Info / Screenshots you need.

Thanks very much and stay Healthy!
