Lucky I was pointed here by someone who saw your message, I only occasionally check bitcointalk. Bug reports and help should go to the github, mailing list or IRC channel, to ensure we see them :-)

Thanks for confirming that the patch worked ^^

Are you trying to connect the daemon to itself? Not sure why you'd do that, and pretty sure we close self-connections, try connecting to some other node on the network (https://explorer.acinq.co/ for (id, ip, port)-tuples)
