I have seen a few examples where my node knows about other nodes, and they know about me, both are online, yet they are not connecting.
Right now only 2 nodes are connected, 11 are disconnected. Almost all of the disconnected nodes are online and using the latest build according to the freeviz page, it is hard to imagine that all of them have change IP addresses or port numbers since I added them. Could there be some kind of problem with nodes connecting to each- other? Perhaps with the keepalive pings where there are a large number of disconnected nodes? Another explanation might be that this is a limitation of my firewall, but I have had up to 5 connections in the past, now i only have 2. Ian.
