DHT Not Connected

Hello, i’m new to bitcomet, i’m having a problem. At the bottom border of my BitComet main window I have what apears to be a Black light (instead of Green, which is what i’m suppose to have), and beside this light it says “DHT Not connected”. What does all this mean, i’m very sure i set up BitComet correctly. I forwarded ports to my router and everything. What is the problem here?
