I have been running full nodes for 2 years. No problem with the firewall, and no problem with the IP, which haven't been changed.

I've got unreachable to other nodes since yesterday. Before all was well, and nothing was changed on my PC, firewall, IP etc. I have also restarted my PC and router a couple of times, but still 0 (zero) Incomming connections on the network bebug window in my bitcoin client.

Can it be a bug on the v0.13.0rc1 ? Should I change back to client 0.12.1?
