How to fix it?

Hi Tamas...
you started it correctly and i'd like to ask if you've followed it up with a couple other steps to just check the situation.
First after the configuration is set up, which you've done correctly, the device usually needs a full restart to begin working.
After the restart, check 'voxl-inspect-services' again to make sure the service is Enabled and Running, just to check.
If that passes the check, run 'ifconfig' to get your ip and post it in a web page browser. Among the available selections should be 'VOA PC' and should give you some positive results.!

Can you try to run the server manually: voxl-dfs-server and see what the output says
