Yesterday, my (main) computer (core i7 based with good DSL; connection test passing 100%) turned into a Hub - and only connected to Peers, but did not allow a single Hub2Leaf connection: There were many connection attempts (every some seconds one) but none of them managed to connect.
I think this can cause the big amount of low-leaf hubs (green) on the picture.
This is why I am repeating my request to implement a new system to calculate the Hub rating...
BTW, can anyone find the topic with my proposal again??? I seem to be unable to find my topic about this again... I've just spent more than an hour and couldn't find it...
