I suspect half the nodes are forked..
The difficulty is to low 10k compared to 20k a few days ago,
I was forked yesterday. I'm good now.
but I woke up this morning to being a dozen blocks behind with 2 connections.
This official node in your config file is outta whack..
addnode=188.68.52.172
tools/peers list
Starting height 154530
Sync height 142845
now 142866
plus some of the nodes are lagging.. 1 or 2 blocks
even with excellent ping times..
block explorer is lagging as well..
